300blackout with 150gr hornady fmj

[handcannon]

I've been loading 150 gr fmjbt bullets in 300blk for quite some time. Once you find the load, very accurate. No I don't seat to the channelure. Puts the bullet to deep in the case and will increase pressure because you are removing case volume.

Had to load to the shortest throat, so they would function in all 3. The seating depth ended up being just past the cannelure.
