Anyone have any favorite loads for 300 BLK for a 10.5" barrel set up? Gonna try some 150g FMJ and 110g loads with H110 and some 220g subsonic with blue dot. This is a new caliber to me, so any tips or tricks on this round is appreciated.
I have a 8.5" barrel and have been running 208g Amax Bullets with 10.5g of H4198. It shoots really well and is around 1050 fps through my can. I haven't loaded any supersonics yet. If you can find it, Accurate 1680 is suppose to be the go to powder for subsonic rounds.
