I have just scored a sweet new rifle from the classifieds here on the 'fire and wondering if anybody has ever loaded for this cartridge.

I found a fair little bit of info on the web by searching its various names (6mm-250, 6mm International) but they mostly utilized powders I don't have. I'd be grateful for loads ya'll have to offer, but specifically looking for stuff using RL-15, -19, and IMR-4350 if y'all have experience w/ such powders.

Thanks a lot,
