6.5G at 600 yards

[LRRPF52]

My 16" AA barrel with 31.1gr of CFE223 under the 123gr A-MAX did 2489fps at 15ft from the muzzle, 60˚F.

31.1 2489
31.4 2520
31.7 2532
32.0 2553

My 17.6" Lilja barrel:

31.1 2412
31.4 2456
31.7 2465
32.0 2530 Notice the velocity spike from 31.7 to 32.0

5 shots from my mass-produced 31.2gr CFE223/123gr A-MAX load out of the 17.6" at 64˚F:

LaRue 18" Stealth 2.0 6.5 Grendel shooting the same 123gr A-MAX/31.2gr CFE223 load:

Howa 22" bolt gun, same load of 31.2gr CFE223 2.253" COL, Lapua brass, 60˚F:

12" 6.5 Grendel Faxon Group Buy barrel

120gr Federal American Eagle OTM factory ammo, suppressed with TBAC Ultra 5:

2360
2375
2374
2387
2384
2411
2398
2397
2349
2406
2384

Average: 2384fps 15ft from the muzzle. For a ballistics calculator, I would plug in 2400fps for that load as actual mv.

Take both of them to the course and have fun. 600yds is boring with any barrel length in 6.5 Grendel if we're talking 2 MOA targets and a good barrel/rifle/optic/ammo combo.

For a mediocre cobbled DIY build with parts I would never use, 3 MOA targets should be doable with a good shooter and good wind calls.
