    Looking for load data for .45 colt and VV-3N37 for a 250 RNFP (Cast lead, MO bullet)

    I do not wish to exceed SAMMI specs of 14k, although this will be shot in a New Model Blackwalk.

    I did find the Handloader Magazine Article that had

    285 RCBS 45-270-SAA cast and using 11 grains of VV-3N37 for ~1k FPS and ~14kPSI

    But this is a considerably different bullet.

    I am not sure that 3N37 is well suited to that application. I looked at the Vihtavuori PDFs and I would have to interpolate some load data, as they do not show any loads with 3N37 and only jacketed with N340 & N350.

    Do you have a faster powder? N320 for instance.

    My Powder options

    Well,

    I have VV tinstar, Clays International, and Trailboss

    and 5 lbs of VV 37 that I would really like to find a use for in the Colt.

    I figured if someone figured out a ~1k FPS for a 250 grain bullet at <=15kpsi

    I would be in 7th heaven.


    On the way from PV I have Uniq and Bullseye and VV N105

    Thanks for the welcome!
