I love to shoot the 45-70 cartridge. I have one T/C pistol, one T/C rifle, and two trapdoors in that caliber. I also have to admit that as I get older I am starting to find shooting sessions to be a little hard on the wrist and shoulder. I read about Trailboss powder and decided to give it a try. The loads were from the Hodgon site
http://data.hodgdon.com/cartridge_load.asp . I started off loading a few with 14.1 gr behind a 300 gr cast bullet. That is supposed to give about 1200fps At the range, the loads were VERY mild in the pistol, could have shot that all day. Went back home and loaded some more. I told this to a friend who has a 45-70 guide gun and was thinking of selling it because he does not find the recoil as much fun as it once was. He and I went out and played with the loads. I only used the trapdoors for this shoot. He shot one and broke out in a laugh, and said that he was not selling his guide gun any more. We then went on to sight in the guns. We ended up shooting 40 rounds, almost all from the bench. We did not actually shoot groups, spending most of our time trying to get the gun on at a hundred. From what we could see, it looked like we were getting 3-4 inch groups at 100, about the best we could hope for with our old eyes and iron sights. Once on at 100, we went to sighting in at the gong at 220 yards. The last three shots all hit that 12 inch gong.
I also loaded a few rounds with 500 gr cast bullets. 8 gr pushes it at 700fps. Recoil was about the same, very mild. I did not have enough to see how it grouped. I just wanted to see how heavy bullets would kick.
I had also brought a 38-55 model 94 that I have had forever, but do not shoot because of the recoil. I do not know if it is the steel crescent butplate, but the kick is absolutely brutal, worse than any of my other guns including magnums. I loaded and shot some with trailboss according to the Hodgdon data. That was the first time that I shot that rifle without wincing every time I pulled the trigger.
Now I am thinking of taking some 100+ year old rifles deer hunting.
