Re: Reload .338-.378KT for Nosler 250gr w/Retumbo
I shoot a 338 Khan which is a 338/378 improved. However it has just a bit more case capacity than the factory 338/378 so I would think my loads would need to be backed 4 or 5 grains to start.
250 SMK / RL 25 - 107 grains / Fed 215M 3240 fps
300 Berger / Retumbo 104 grains / Fed 215M 3018 fps
250 SMK / Retumbo 111 grains / FED 215M 3230 fps
I am a fan of SMKs and Bergers, don't have any data on the bullets you mentioned. One new bullet I just started messing with is the Cutting Edge 225 grain.
This may not be my final load as I still want to play with some other powders.
225 CE / RL 25 108 grains / Fed 215M 3400 fps
Good luck, and be careful...... start low, if you try any of these loads.
