If you shoot a 454 C you can shoot a 45-70. I have a Contender 14" 45-70 w/break and it is not as bad as my uncles 454C. The Encore would be a little heavier and should reduce some of the felt recoil. If you are hunting whitetail, bear, elk or game about the same size, you can use a 300 grn bullet and have all of the power you need and not have to worry about it splitting you forehead. The 300grn Sierra Jacketed Hollowpoint shoots great from my barrel and I have taken deer and hogs with it.
If you are going to Africa, I guess you might need one of the heavier bullets. :eek:
