Maybe the barrel finally "came in", but I also started playing with bench technique. An AR just handles different in the bags than a bolt gun and for me I have to watch things more so than with a bolt gun.
Having said all this and now having a good bench technique with the AR, the 55gr Sierra and Nosler are giving 5/8" to 3/4" at 100yds consistently ...the Berger 52gr Target and Varmint are giving 1/2" and smaller...a few groups in the .3xx range but consistently 1/2".
If I could consistently get .5-.75” 5 shot groups I’d be happy. What kind of velocity gain am I looking at if I jump up from a 20” to a 22” barrel shooting the 55 game kings? 3600 for 20” and 3650 for 22”? Or higher?
Standard or light profile? Used for hunting and shooting off a tripod. Weights not a huge concern, I’d rather have accuracy but don’t want to lug around a pig either.
Is this what most people are using:
Bullet: 55gr game kings
Powder: CFE223
Brass: Hornady 6mm Hagar
Primer: small rifle 400 or 450?
Dies: I saw nosler and RCBS anyone have the model number so I don’t F it up?
What’s my trim to length on the brass?
BCG: 6.8
Mag: 6.8 ASC or what’s the choice here?
