Anyone reloading Sierra GameKing SBT 55gr for AR

Check their site. Most projectiles manufacturers have a safe load amount for you to get a baseline with.

I tried their website but no info, I think I'll be safe to load them at 2.250". Thank you all!

Ive loaded at 2.26 in AR in 55gr fmj and I believe hollows and softs but without looking at my notes cant say for sure for that projectile.
As long as it feeds and chambers fine the extra length wont be a function issue, but may affect velocity and possibly accuracy.

Hey Woody, whats a good hand load for wylde chamber for distance any issues with running them hotter with 80 gr sierra bthp
