does anyone have experience loading boolits in 300 blackout? I have 10,000 115gr cast, gas checked .308 boolits that were given to me, and am casting 230 gr from a Lee mold for subsonic. If the 115's won't work, I'll melt them down and recast as 230.

any advice would be appreciated.

Pointed or FP? Pointed might feed in an AR, but I have been having trouble with FP boolits. Also, .308" might be a bit too small in dia. for good accuracy.

It seems like everyone's go to in that caliber is H110. I'm loading frangible 108Grains with that powder. Gas checked should help, but I started low and moved upwards to see how the function is in my AR. Mine didn't cycle until I got several grains higher, but I never did have pressure issues. I got my data from the 300BLK forum for starting points.
