get a mold that weighs 475 grains, it will shoot way better than the 550 one. pm me and let s get you winning every match. if the new mold at 475 grains has a cupped base , so much the better. it helps bump up a pp bullet. i also have a reamer you can borrow to free bore the first 1/2 inch of your bore at the throat of it. that way you pp patched bullet will enter the barrel with out a tear or ripple on the paper. never a need to wet patch with my method. my freebore is .459, 1/2 thousands above the bottom of my rifle bore. get wads from close to you at buffalo arms. get number nine all wood fiber paper also. 209 powder is not cheap but it is worth it many times over. you can use reloader 7 also and set the bullet back in the case so no void. belay that, dont use reloader 7 in your case, too long, i was talking about a 45/70. as to recoil, easy fix. go to mid way and buy the best dead mule they have and install it in your back stock under the butt plate. that will change every thing in a instant. you have a very good high end rifle, put a little money in it and make it a real shooter. pm me i love putting guys in the winner circle. i have other tips also. remember, i have helps 2 brothers get 3 inch groups at 500 yards shot after shot. they were using blackhorn 209 powder and a paperpatched dry wrapped bullet. boy did they make some old stiff guys mad shooting their heavy greased bullets. the old guys said it was a fluke. well im a old guy and it isnt a fluke.
