Load testing the 45 Colt for a hunting load

I want to use the 45 Colt in a combination of a Freedom Arms model 83 pistol and 45 Colt Winchester 1892 for some hunting this upcoming season.  So I made up some 340 grain bullets and tested them over the range provided by Hodgdon for H110.  Since the bullets are 348 grains as cast, and about 358 grains with gas check and lubed, I used the 360 grain load data.

Loading data for the 340 grain boolits
  • Projectile are cast lead 'boolits'
  • 340 Grain Long Flat Nose (LFN) Bullets
  • As cast weight 348 grains
  • With gas check (Lyman) and lube they run ~358 grains
  • Alloy was a mix of 9 lbs lead, 1 lb linotype, 1/4 cup birdshot (for arsenic).  Bullets were water quenched after being cast in LBT molds (thanks Veral Smith of LBT).
  • Sized with Magma sizer to 0.454, LBT blue lube
  • COAL 1.66" (originally tested at 1.67" but slight hesitation in the Lever gun suggested a slightly shorter COAL, the powder is still not compressed)
  • 21.0 grains of powder H110 (18.4 to 21.0 grains tested)
  • Bullets must be crimped for both the Winchester and the Freedom Arms
  • CCI 300 Large Pistol primers
Everything shot great (but I will shorten them just a bit to 1.66" to make sure they feed better in the Winchester) and the next step will be to chronograph them and get the guns zeroed with them at 50 yards.
