That is quite a project - thanks for sharing it with us in such detail, Birdhunter50.

Further to that load - the black powder .45/90 load of the 1880's was a 300gr. bullet at approx. 1,584fps.

1,584 is exactly the velocity Ross Seyfied's .44 mag. pressure for .45 Colt loading gave me in a Winchester Trapper 16" bl.

I shot 2 elk with that load using an RCBS 300gr. HP (my mould conversion) cast bullet. The elk were approximately 80 and 100 yards distance.

There are no flies on that load for most big gamed shooting.
