Believe the Lyman Trade Rifle has a 1-48 twist that should work with a 450 grain Plains Bullet, but for some reason it’s tumbling. What diameter is your felt wad? What powder are you using? Just for giggles and kicks, have you tried a patched roundball?Shooting a Lyman trade rifle in 54 cal. Lyman 450 gr. Plains bullet and getting tumbling at 100 yards. Is the rifling to slow for this bullet? I am loading 80 gr. 2f and using a felt wad.
Sounds like the Hornady 425 grain is the conical that your gun likes with your current setup. You may want to try larger diameter felt wads, 5/8” and 9/16” may seal the bore better. Personally have found larger than bore wads more effective than actual bore size wads, but that’s something you will have try for yourself in your gun.Yea round balls shoot good. 54 cal felts.. Got drawn for elk so thinking a heavy bullet would be best. It shoots the hornady 425 gr. Buffalo bullets ok but they are a little shorter in length

Sounds like it to me. Experts will chime in about the twist rate, I have no idea what it is but it's not enough.
If the twist is 1 in 48 than your bullet must be to small of a diameter to catch the rifling. If your casting them yourself add some antimony from wheel weights and this will make them shrink less when casting and yield a larger cross section diameter. It will also strengthen the bullet alloy to resist stripping in the rifling.Yea round balls shoot good. 54 cal felts.. Got drawn for elk so thinking a heavy bullet would be best.
