My bore is 0.429" so I had some cast 44Mag boollits at 0.430" on hand, but due to the original heeled boolit design, with the added case neck thickness ... they would not chamber. Using a friend's trick, who loads for a Swiss Vetterli, I sized them down to 0.426" and they work perfectly! I too NEVER need to size the cases and shot 20-40 shots each weekend.
I had better luck with 16.6-grains of Alliant 2400 and shot an incredible (witnessed) 3" group with it offhand one day at 100-yards. Let's just say that with a 150-year old rifle ... that the Capt of our Club's rifle team asked me to join his squad! I have not duplicated or bettered that feat ... yet. I also tried SR-4759, expecting good results, but they were 'meh' ...
To start out, I put a dental elastic ahead of the rim and fire-formed the cases to fit the chamber perfectly. Now I just decap, add a new primer, add powdah, seat/crimp (lightly!) boolit and go shootin'! As a bonus, I only paid $200 for it, toot schweet!
Next up ... some black powdah loads for it!
