do you usually get around 3 failures in 100 rounds?

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.

it probably wasn't a coincidence since the heavier spring will increase back pressure raising FPS

That's kind of what I figured too but this time I also went with the same and lower charges & still no keyholes. I am going to load up some of my past loads which had a lot of keyholes & see if there are any changes. Now I'm curious :ponder: :D

I'm wondering, have you tried SS197 rounds with the new spring yet? I'm going to have the 20lb spring installed when EA does the accurizing. I carry S4Ms now which should be no problem, but I primarily practice with SS197s and I'm just a little concerned about FTEs...

I have used 197s & they cycled fine.

Next Saturday I will be going to the range with a few hundred rounds of 197, about a hundred rounds of S4M and all new springs from EA. I will report back on how it works out. If I have issues with the light loads and the HD spring I will just swap out the 18lber when im using FNs loads...

Feedback to come.

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 want to make one thing very clear. My Fiveseven is ridiculously and indefinitely dirty as hell. I treat it like a Glock. Not only from shooting but from Kydex dust. Take everything I post with a grain of salt since im sure my Fiveseven isnt like yours...

I can't wait to try my new springs and lip protectors out too :). I am mostly liking the shorter toss of the brass!

I'm not really seeing the reduced distance that I have to chase the brass :laugh: I measured mine today, 8 yards (avg) using 197s & still a helluvan arc :laugh:
I tried more low power loads (subsonic) & had no FTEs this time. I guess my old problem loads are just that - problem loads :(

The main reason I am posting here though is that, on average, I am seeing about a 10fps increase in velocity using 197s & I've used 3 different lot numbers of them.

EA needs to make a brass catcher :thumb: I'd gladly take my laser off and attach one to the rail :)

The rail isn't meant for that kind of stress. IIRC, Vitally had one on his & it cracked his rail. But the brass catcher topic has been covered before viewtopic.php?f=15&t=389" onclick="window.open(this.href);return false;

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.
