Hi,
Does anyone have any experience with VihtaVuori N-340 powder ?
I'm trying to develop .45 Colt loads with 225 Gr plated hollow-based bullets for my 4-5/8" Ruger Blackhawk, say around 900 fps'ish.
The closest I can find on VIhtaVuori's own site are loads for 200 Gr LSWC (10.9 gr. to 11.6 gr., for 1100 to 1200 fps) and 230 Gr FMJ (9.7 gr. to 10.4 gr. for 990 to 1100 fps)
The bulletmaker's site (H&N-sport) only lists loads with N-320 powder (which is quite a bit faster than N-340 more like W-231), namely 6.0 gr to 7,5 gr. But assures me those bullets are loadable up to & beyond 1000 fps, depending on gun & barrel length.
Any ideas ?
