Hi guys. I ordered a American ranch rifle in 300 Blackout and am having problems finding loads. Most all the loads i find are for gas guns. I would think there would be a lot more info on loads for a bolt gun. I have found a few. I'm looking for super loads not sub sonic. I want to take advantage of the caliber. I have H110 IMR4227 but there must be more lodes out there. I have a good supply of Alliant 2400. Unique and red dot. I have a Noe165 gr cast ranch dog mold and a lee 309 170 gr flat point mold and a 200 gr Lee spear pointed mold. I emailed Aliant powder and they gave me The speer web sight which helped a little. Have any one here have any luck using any other powders for a bolt gun?
