I have a Slufoot converted H&R 45/70 barrel in the mail headed my way. BH209 is an option, but I wanna give smokeless a try. Im looking to shoot 180 grain--200 grain 40 cal bullets. I dont need 2500 fps. Most of my shooting is at or less than 100 yards. So I d be happy with 1900--2000 fps. Also this is going to be a lightweight rifle for treestand use. Let me know what works for you.
Looking for load info for 45/70 conversion

If thats all the speed you want, look no further than about 31-35gr of SR4759, N110 or maybe 5744. IIRC around 38gr of 4759 is getting close to 2400fps.
Ok shot the 45/70 conversion today. I was a bit rushed, I had my 7 year old with me & it is cold out. I went with 45 gr of H4198 crush rib sabot & 200 gr SSTS pretty happy the way it shoots so far . I wanted to try some other combos, but the boy was getting antsy.

Nice shooting! :yeah:
Running 4198 that low will cause pressure (lack of) and you'll have issues with ignition.
Can you get your hands on any shotgun powder? I realize 4759 is discontinued but if you can get your hands on that, it would be the way to go. I'll look at some load data and see if I can find anything.
