First Grendel....

[VASCAR2]

Don’t buy all the 6.5/.264 bullets at Sierra mdewitt71! Buddy and I try to make a trip to Sierra at least once a year. Plan on going by Starline this trip. We usually stop at Graf’s in Mexico Mo on the way home. We were planning on going in the next couple of weeks after the weather improves.


I used Xterminator to load 5.56/223 55 grain FMJ and has proved to be pretty accurate load with PPU bullets. Buddy bought a bunch of 55 grain FMJ PPU bullets at a good price and sold me 1000.

Thanks mdewitt71, looks like 123 grain ELD-M velocity is lower than the A-Max I chronographed in a 18” Satern/Liberty barrel. I’ve gotten good results with Xterminator with 85 and 90 grain bullets in the 6.5 Grendel.

OK, 2nd Range trip with the 18" Grendel and my speeds picked up and my SD lowered a bit for the Black ELD-M factory ammo.
I got 2405.6 FPS with a 13.2 SD in a 20 shot sequence.
I also shot the American Gunner factory 123 HPBT at 2380 FPS with a 15.1 SD.

How did the American Gunner group compared to the Black???

Not as good as the Black.... but, better than Wolf for sure.
My groups this range trip was nothing impressive, hope to do better next time.

American Gunner velocity averaged 2380 FPS with a 15.1 SD
There was about a 10-12 MPH crosswind and it wasn't shooting spectacular at 100 but, OK for only the 2nd trip with this build.
I was blasting 6 inch gongs great at 300 with it.



Hornady Black gave me a 2,405 FPS average velocity with a standard Dev of 13.1 out of 40 shots fired.
The velocity went up and the SD down from my First range trip on this same barrel, good break in sign.
I shot three or four groups but, most were not that great, with the best being below.



It's not a match grade barrel nor a $1000 build so I don't have any complaints right now....except my next day off is not for awhile.
