oooo... me me me me me! I take it I could potentially (at my own risk) use stronger loads w/ this? Do you guys need to install it?

Self install or need to send it out? Any disadvantage to the heaiver recoil spring? What advantages (assuming the one in the gun isn't worn out)?

None it works fine with EA sub sonic. It may be less reliable with SS197 but I don't care about it working with that.

Buffman wrote: What advantages (assuming the one in the gun isn't worn out)?

The same as any other handgun when you install a HD spring. Slide bangs less and brass only fly's about 5 feet instead of 15 to 20.
When I talked to the engineer in detail about the factory spring he noted after analyzing the factory spring that it's not made out of anything special and it's duty cycle is that of any other spring. So anyone with more then 10k on your reciol spring your spring is already wearing out and allowing the slide to beat up the frame.

Post by **Grantness** » 26 May 2011, 18:05

Can you speculate as to whether these are gonna work with the new longer fsn barrels or would they potentially need something even stronger?

Im trying to figure something out in my head and since Im no engineer and i've thought about this for roughly 2 minutes... Im not sure what to think: when we modify AR57's & PS90's to take heavier loads we cut down the springs a little (making them weaker I assume) and add weight to the bolt. Since the FsN spring is stronger (and the slide which is blowing back remains the same weight) why is it different?

I will put them up on the website Friday

Post by **panzermk2** » 26 May 2011, 18:16

It holds the slide closed longer. It could in theory allow for hotter loads but as always with the 5.7x28 it's the primer is the weak link in the chain.

I don't know about cutting the springs down on a PS90 only adding weight to the bolt. Of which I am still waiting on my bolt weights.

If the primer is the weak point, and you add the appropriate modified parts, could you potentially begin gluing the primers on 5.7x28 and getting HOT loads?

No because the primer cup itself fails and you get pierced primers.

Post by **Grantness** » 26 May 2011, 20:59

Tangling with glued and blown primers isn't worth it IMHO. Might be bad for the gun over the long haul if nothing worse. The are plenty of good loads to use that aren't pushing overpressure. Frankly, I've never felt the desire to spend all that extra time anyways...

Well people like Wolf make HD and light duty target springs for the 1911.

There are times SS197 WON'T cycle a stock FsN pistol, kinda hard to make a HD spring that it can cycle.

Like I said I tested it with hundreds of Sub Sonic 5.5 ammo and it ran fine. So it should be OK as long as the SS197 is not a low power batch.

So in other words, HD spring is good for suppressed use because it resists the extra back pressure, right?

If so, would you guys consider like a 22 lb spring for peoples threaded barrels?

Post by **panzermk2** » 27 May 2011, 09:35

Nope there would be cycling issues. The can increases pressure but only slightly no where near full power loads. Plus there are other issues, you are dealing with a blow back system and unlike a browning system there are many other things that have to be taken into consideration when increasing the spring rate. Plus on the FsN the springs has to be able to fit inside the barrel shroud.

im sure thats just an automated message that goes out for everything considering 99.9% of the stuff they sell is ammunition.

Lisa, so that means that my spring will ship on Friday?

Also, I was wondering about FOID laws. I have mail ordered ammo before and from some places you need a FOID while others do not seem to care. Is there something in the law that makes it different if you have a physical presence in the state of Illinois?

Nope the other places are screwing up BIG TIME by not asking for a copy of you FOID card.

bobapunk · Post by **bobapunk** » 30 May 2011, 18:44

It has been a pain since I moved. I updated my address with the Ill. State Police and they told me not to bother with getting a new card until I had to renew. This caused major issues with Gander Mtn and Cabela's; but no local shop even questioned it.

I am mailing in my renewal tomorrow, so as soon as I get my new FOID card things should be smoother.

Just installed my new EA Recoil Spring....and damn am I happy! :monkey: :monkey: Took me about 5 minutes to put it on. I'd recommend a good cleaning and lube job while you're at it...

I fired 30 rnds of Blue Box SS195 from a 30rnd extended mag w/ the EA mag spring. Did not have the time to set up the chrono today, just checking for function. The first three rounds had trouble feeding. The slide would get stuck about half and inch out. After clearing and checking everything... I fired the rest without indecent. Even tried some rapid fire. No problems.

First thing I noticed was a definite increase in recoil w/ those wimpy blue box SS195's. As advertised, the cases only flew 5 yards AT MOST. Usually less. I am more than impressed.

Another success for Elite Ammunition! :clap:

Can't wait to try out a whole new set of reloads and see what this baby can REALLY do :ponder:

Post by **Grantness** » 21 Jun 2011, 15:25

...oh, when I was at Lowes getting some supplies I asked the guy if he had the right kind of pliers that I needed. He asked me what it was for, so I showed him the barrel. Guy whips out a knife and proceeds to take the spring off. Almost had a panic attack. Bastard took a knife to my baby w/o my permission. ...BUT, I'll give him this. He got it off, didn't scratch or break it, and there was one less tool I needed to buy!

Post by **Grantness** » 22 Jun 2011, 13:19

Took my new EA Fiveseven Recoil Spring for a test drive today.

Blue Box ~27gr SS195: 1883, 1872, 1888, 1907, 1910 AVG: 1892fps

40gr Nosler Ballistic Silver Tip, Blue Dot: 6.7gr, OAL: 1.180" CCI 400 Primer

1875, 1899, 1918, 1921, 1940 AVG: 1910.6fps

Checking back on my old notes, I had an average of about 1890fps for that same load with a regular 40gr Nosler Ballistic Tip. It struck me as odd that the rounds tended to increase in velocity the more I shot...

Probably a fluke. Not a large enough sample size yet to make a definitive assessment.

More to come

spartacus · Post by **spartacus** » 07 Jul 2011, 05:10

I got my new recoil spring in a couple weeks ago and brought it for a test run last week... I'm sorry to say that I was very disappointed. I have never had a failure to feed in that gun even after thousands of rounds without cleaning it. I put the new spring on easy enough, gave the gun a good cleaning, and went out to the hills to shoot. I went through 60 rounds with the new recoil spring and had it jam 3 times. Any suggestions to fixing the problem? I was using some fairly light loads, 40 grain v-max with 6.8 grains of AA7, are the loads too light for the new spring?

Post by **panzermk2** » 07 Jul 2011, 06:06

Your loads are too light.

It is a Heavy Duty 20 pound spring instead of 18. What made you think it would work with light loads?

HD springs aren't for light target loads.

I can make light duty target springs just like there are for other guns but I do not think the demand is there.

You also should think about cleaning your gun more often.

Post by **Grantness** » 07 Jul 2011, 08:21

Shot mine all weekend and it functioned flawlessly....even with blue box ss195.

spartacus · Post by **spartacus** » 07 Jul 2011, 08:26

Correct me if I'm wrong but that light load should be slightly hotter than factory loads, does this recoil spring not work with factory loads? I knew the spring wouldn't work with light loads but I assumed it would at least cycle with the standard factory loads. I typically shoot hotter loads anyway so it's not a huge deal, but it may be something that should be addressed on this little thread if that is the case. I'll be reloading some hotter rounds soon and see how it does.

It also seems like the new spring has a slightly larger outside diameter than the factory spring, the barrel now sits off center in the slide and there is a small gap in between the slide and frame, is this normal? I dont think it's anything more than a cosmetic issue but just making sure.

One more question: Shouldn't the heavier recoil spring increase the life of the brass? The spring should hold the slide in place longer causing less stretching of the neck... right? Just curious.

I typically dont go that many rounds without cleaning my gun, I did shoot a couple thousand without cleaning it one time and was quite impressed that even then the gun functions flawlessly.

spartacus · Post by **spartacus** » 07 Jul 2011, 08:33

Grantness, you mentioned that yours jammed the first few rounds with it, what did you do to fix it?

Post by **Grantness** » 07 Jul 2011, 08:46

I've chalked it up to the particular 30rnd magazine I was using. I've had problems with it before. That being said, only the first two or three rounds had problems. If it had something to do with the spring, it worked itself out in a hurry. I agree with Jay: clean up again, and try a stronger load. Western Powders lists 7.0gr of Acc#7 for their minimum load on a 40gr Sierra. Like I said, I had no problems all weekend with even the weakest of factory ammo. ...But I didn't buy the HD spring to see how it handles weak ammo. I intend to explore the other end of the spectrum and find out how much max loads may or may not increase.

spartacus · Post by **spartacus** » 07 Jul 2011, 08:57

That's what I'm planning on doing, but will be slightly disappointed if I cant use target loads with it. On Accurate's website they list 6.8 as the max load, I do acknowledge that it is no where near a heavy load but it should still be hotter than a factory one (should be going just over 1800fps according to data).

Post by **Grantness** » 07 Jul 2011, 09:02

I dont see where you're getting this. Im looking at their load tables right now. They list 6.5gr for the Max load for 40gr using Acc #5. For Acc#7 they list 7.7gr as the max load....7.0gr is the MIN. I happen to know that you can go even higher than 7.7gr. I've also found out that the velocity figures they put out are significantly faster than my own results.

Think back... did 6.8gr FEEL like a max load to you?

spartacus · Post by **spartacus** » 07 Jul 2011, 09:19

Look a little bit lower on their data, they have a specific load for the hornady v-max, for some reason they say it creates a lot higher pressure than the other 40 grain you are looking at (45,100 PSI with 7.7 gr vs 48200 PSI with 6.8 gr):
5.7x28 FN
Barrel: 5" ■ Twist: 1-9" ■ Primer: WIN WSR or WSP ■ Bullet Diameter .224"
No.5 35 HDY V-MAX FB 6.0 1,955 6.7 2,100 45,500 1.491
No.5 40 SIE SPH 5.8 1,850 6.5 1,975 45,200 1.456
No.5 45 SIE SPH 5.7 1,740 6.4 1,875 45,400 1.490
No.7 35 HDY V-MAX FB 7.4 2,041 8.2 2,197 45,200 1.491
No.7 40 SIE SPH 7.0 1,896 7.7 2,044 45,100 1.456
No.7 45 SIE SPH 6.7 1,782 7.4 1,913 45,400 1.490
No.5 40 HDY V-MAX 5.1 1,657 5.7 1,875 48,000 1.580
No.5 45 SIE SPT 5.0 1,558 5.6 1,746 47,800 1.580
No.7 40 HDY V-MAX 6.1 1,679 6.8 1,880 48,200 1.580
No.7 45 SIE SPT 5.9 1,568 6.5 1,782 48,300 1.580

I'm not even trying to argue that 6.8gr is a max load, I'm just saying it should be at least comparable to a factory load so I would have assumed that the spring would cycle with it. I agree that the velocity probably isn't what they publish but from what I have seen the factory ss195 doesn't pass 1700fps so even if accurate embellished the data by 200 fps (they publish it at 1880fps) then the two rounds should be pretty comparable. I haven't chrony'ed those loads or anything so I guess it is possible...

Post by **Grantness** » 07 Jul 2011, 09:34

My print-out doesn't have any of that, but I cut off the "special notes" because they were either obvious, irrelavant, or just plain wrong. *Want to see just plain wrong? Check out that Lyman manual :lmao:* Ignore what they wrote. If anything, the VMax will do better. Clean it, lube it, try it out with something closer to 7.0gr or greater (if you aren't interested in stronger loads) and see if you get the same problems. I've personally gone a bit over 8gr w/ Nosler Ballistic Tips. Or better yet, get some SS195 blue box (the weakest round they sell thats not subsonic) or SS197 and try that out. Do you own a chronograph?

As Jay pointed out...the whole reason for an HD spring is to increase velocity and handle stronger loads (not to mention the shorter brass ejection distance). If you want to shoot min or less than min target loads, just swap the springs out...doesnt take long w/ the right tools and techniques.

spartacus · Post by **spartacus** » 07 Jul 2011, 09:48

Thanks for the help Grantness. I typically shoot stronger loads but do load up some target loads once in a while for plinking, I'll test it out with some ss195 and some stronger loads to see how it does. I might just have to go with a little hotter load for plinking.

Did you start to see any signs of pressure when you loaded the v-max past 7.7 grains? I'm kind of scared to push this round from all of the stories of the round being so finicky, I've gotten it around 7.4gr with no pressure signs but haven't dared go much higher.

Post by **Grantness** » 07 Jul 2011, 09:55

Well, first of all there are ways of detecting overpressure-signs. I wrote an article easily found in the reloading section of the Wiki. But common sense it the main thing. If there's too much kick and freaky black smoke coming out the back (along with pierced primers and such)...then you're pushing it. Second, iFire recently described a difference between "new" and "old" acc#7, which might explain the discrepancies i've seen between their posted loads and my own results. If you're powder is relatively new (within 3-4 years or so) then its probably the new manufacturer...and you can use higher max loads. Third, loads posted by major companies usually err on the safe side for legal reasons. Fourth, don't quote me on this, but I doubt you could fit enough powder in the case (uncompressed) to cause problems

Fifth, the HD spring theoretically ought to allow for a higher max load.

On the light load topic - I installed the new spring (very easy procedure if you can manage that smeggin' snap ring) and feed lip thingies this week & took it all for a drive today for subsonic testing.

Out of 105 low power rounds, I only had 3 failures to eject & I think 2 were because the brass didn't get the case lube cleaned off well enough & it was just too dirty to eject. There was one feed jam but that was because the feed lip thing didn't stay put.

do you usually get around 3 failures in 100 rounds?

Post by **Rapier1772** » 30 Jul 2011, 17:46

Short version - 3 is less than I was expecting.
When developing subsonic loads, I've learned to expect FTE. With the higher tension on this spring I expected more but I only had 1 real FTE (I am blaming my lack of proper case cleaning on the other 2 since the cases tried to stick in the chamber). If you look here viewtopic.php?f=19&t=5715&start=20" onclick="window.open(this.href);return false; at the Oct 1, 2010 post - I had a ton of FTE & that was a factory spring.

On a strange coincidence note: There were no keyholes today. Usually with this kind of load I see at least one or two.

So I got to the range today. Virgin HD spring, Mag springs, and feed lip mods. First up was 150 rounds of SS197. Not one problem feeding, firing or ejecting. Next up was 50 rounds of SS192. Same as the last, no problems what so ever. Next up was 100 rounds of S4M. Again, same as the rest. No problems at all. Last to go was 50 rounds of Protector. blew threw that with no problem.

I tried more low power loads (subsonic) & had no FTEs this time. I guess my old problem loads are just that - problem loads

I ran 100 197's through my FsN with a brand new EA 20# spring today. No problems at all. I also ran a mag of staggered ProII and ProIII's after that. Again, no problems at all.

As for the ejection of spent brass, I'm not sure how far it would go considering I was shooting at an indoor range. I am very happy to report that it no longer bounces off the wall and hits me in the head though. :clap:

Yesterday night we shot 200 rounds of 97, 50 rounds of 92 and 50 rounds of S4M with out one problem with the HD spring. all my brass was in a nice pile about 6' in diameter about 10 feet away from where we were shooting. And by 9pm at night the 18'' of fire coming out of the fiveseven from the S4M was awesome.

My last update on the HD spring for those still wondering about how it shoots with lower powered rounds. Since my last update on Sep 25, I have shot 1000 more rounds of SS197 with zero issues out of the fiveseven. The conditions were from an indoor range kept at about 72*F all the way down to 35*F When we shot out at the farm at night 2 weeks ago. The spring has performed as advertised and has had no problems.

The fiveseven that was used was accurized by EA and all mags have HD springs with lip protector.

I would say this spring is officially G2G with all Ammunition...

Does this spring work well with the factory loads.

Yes many users have posted their results.

Merged with original thread.

I've ran just about everything EA and factory has to offer, even EA's <1000FPS VAR II, and all have cycled the slide with the 20lb spring.

Is the 20 lb HD recoil spring supposed to be shorter than the stock spring?

Post by **panzermk2** » 24 Jun 2014, 14:36

Not supposed to be anything compared to the factory spring other then properly fitting the action and stronger.
