.........since they give no data on their website? And none of my manuals lists their powder..
Some manuals give pressures of various loads. For the 45 Colt in the 1873 Winchester max pressure is 14,000 psi.
But there are no such guidelines for Vihtavuori powders, and I'm wanting to use their N340 powder for 45 Colt 200 grain plated.
Their starting load for the 200 grain lead bullet is 10.9 grains for 1119 fps. Max load is 11.6 grains for 1194 fps.
I'm curious because they have a whole different category for cowboy shooting and don't even list the N340 powder. They list the N330 powder 8.0 grains at 876 fps. Max for N330 is 8.6 grains at 978 fps.
Is that because of the parameters for cowboy action shoots? Or is it because the 1873 action and the Colt SAA is too fragile for anything more?
BTW, both Berrys and Xtreme say their standard plated bullets are fine for any velocity up to 1200 fps.
