I received some paper patched bullets from another member to try in my .45 GM LRH Hawken barrel before I went and sunk some more money into another bullet mold.
Using his suggestion as a starting load (64.5 gr of Pyro P by weight) and then the same volume of FFFg I shot 2 groups at 50 yards. The Pyro P put 3 shots into 1" and the FFFg just under 1 1/2". Sights were a Williams FP peep and a FO front sight.
Being pleased with those groups I then set the target out to 100 yards. Using the same loads the groups were both about 2 1/2" for 3 shots. The drop from 50 to 100 yards was right around 3"-4".
After coming home and thinking on it I installed a globe front sight onto the barrel and put in a fine crosshair insert. That should improve the "aimability" of the rifle with these old eyes.
I'm still amazed that such a loose fitting bullet could be so accurate. By loose I mean that if it weren't for the veggie wad under the bullet the weight of the ramrod would be almost enough to seat the bullet! Now I have an accurate bullet without any barrel leading.
I still have some more load tinkering to see if I can tweak it some.
