Gust got my e-mail flyer from Midway and in it was some copper/tin composite core 36 grain varmint grenade bullets from Barnes. I then looked through the search section and did not find any info. Has any one loaded this bullet yet? And if so what were the speeds, pershers, and the rest of good stuff? I will serch again to make shure that I not asking something that has already been asked. ( I have rarely seen some thing about the 5.7 system that has not been answered on this site) Any way thanks for the help.

I would treat it the same as the 35grn VMAX. Start low, work up. I am not familiar with that particular projetile, but heck, there are so many out there one cannot possibly know them all.

Buy a box, experiment, report your findings here. Thats how its worked in the past :)

From Barnes web site:


Celebrating its 75 th Anniversary, Barnes Bullets® is introducing the Varmint Grenade™, an all-new lead-free varmint bullet that delivers explosive results. Originally developed for military applications, the bullet’s copper-tin composite core is highly frangible, greatly reducing the chance of ricochets. The new flat-base, hollow-cavity bullet remains intact at ultra-high velocities, yet fragments explosively on impact. Virtually vaporizes ground squirrels and prairie dogs, even at extended range. The bullet blows up completely at high speed, creating little or no exit wound on larger animals. Leaves coyote and bobcat pelts virtually undamaged. Delivers sniper-like accuracy for dependable long-range kills.

In my opinion they are kinda pricey, being new and all, but I have been tempted to pull the trigger on a box the last couple of times I ordered from Midway. I have fallen in love with the Sierra 40gr hollow point for over $3 a box less. I am currently attempting to work up a load using 30gr Calhoon Double Hollow points. I love th DHP in my CZ Hornet and have high hopes for it in my 5.7's.

I almost ordered a box. I did not catch the part about the copper tin core. It would be interesting to measure the length of this bullet. It might indeed turn out to be a good 5.7 projectile.

I have been having good success with the 35 grain V-Max, and recently ordered more. I am trying to keep my eyes open, but good, cheap, long, light bullets are not common.

Picked some up the other day - haven't come up with a load for it yet, but here is a comparison pic

From L-R, CT Ballistic Silvertip 40gr, Barnes 36gr Varmit Grenade, 30gr Berger HP, 35gr Vmax.

The Grenade is about the same length as the 40gr Vmax (or in this case silvertip). It has more bearing surface, but it is a flat base.

Cheers,
Madoc

It has been awhile since my last post when I blew up my fairly new Five-seveN with hot reloads. See: http://fivesevenforum.com/forums/showthread.php?t=5784 Still have not received my pistol back from Browning where it was sent for repairs, so I just bought a new one. Never seen an armored car in a funeral procession yet.

Tried these new 36 gr. Barnes Varmint Grenade bullets and really like them. Loads easy, accurate and makes a very nice looking reload. It is a little pricy just for plinking but should make an excellent hunting load. Midway sells them for $37.49 per 250 which is 15 cents each. I've also purchased from Midway the 40gr. Hornady V-max for $31.99 per 250 which equals 12.8 cents apiece. Think these are also a bit pricy just for plinking.

Now for load data and results: Once fired cases were trimmed to 1.128, primers were WSR, powder charge was 6.5 gr. HS-6, and COL was 1.585 (nothing new here). Average chronograph readings for 20 rounds was 2003 fps. SD was 72 which I feel was high. However, after firing 20 factory rounds of SS195LF, I calculated an average velocity of 1979 fps. with a SD of 64. Think I remember a prior post when someone reported a SD of 30 with factory ammo.

Probably need to run the chronograph readings again. My Chrony is a Beta model which I pulled out of mothballs, lost the manual and actually forgot how to use it. One major error made while recording all the above mentioned readings was they were taken only 3 feet from the muzzle. Wondered why my diffuser shades kept coming off after 2 or 3 rounds. After these initial test with all the frustration involved, I downloaded an instruction manual from the Chrony website. When all else fails, read the instructions.

I hope you don't think that's a warranty repair. :)

I also hope you won't be offended that most will shy away from your loads after what you did to your pistol. :)

That's always a good idea. :D

FOR BTOWN 02

Thank you for your comments. I deserved them. I'd like to treat you to coffee or lunch.

Just sent a check to Browning for repairs to my first Five-seveN. When it is returned, I'd like to start experimenting with Hodgdon Longshot. Has burning rate similar to 3N37 and True Blue and apparently only one other person has reported on it so far.

Have a great day!

I have been trying Longshot in 10mm and 9x23mm, but have not had time to do anything with it in 5.7, so I am eagerly awaiting your results.

So many powders, so many bullets, so many guns, so little time.

It may be another month before I can drive to any place that sells Trublu.
