i have a bunch of these sitting around. they were for my 300 win mag for target loads but i don't shoot that much and when i do it is just to check my hunting loads which are a different bullet. anyhow i figured i would give them a try in my 300 blackout. i don't have the new hornady manual and my nosler #7 book does not cover 180's here is what i found on the blackout forum Hornady SST....... 180gr.... WSR.... LiL gun.... 15.0.... 1720.... 2.098 was thinking about loading a few at 14.5 and a few at 15 and testing them. anyone tried this load?? or any other suggestions. also have some hornady 150gr sp's i want to load in it. was thinking making a few at 15gr and a few at 15.5 (lil gun, wsr, 2.07) any info would be great.
