I have an old Ishapore 2A1, that I want to experiment with. I want to get some 'super-heavy' cast boolits, 300 AAC Blackout 245 grainers, and see what kind of accuracy I can squeeze out of her, I am looking for a relatively low speed, hopefully subsonic.
I cant really find any data about using 300 Blackout bullets in 308 Winchester cases.
I have some BlueDot, IMR4227, IMR4064, IMR4831, RL-15, N-140, FFg Pyrodex, IMR3031, and IMR 4198 to play with... thoughts?
