I have shot Winchester jacketed hollow point 300 grn and I use Hornady 325 grn lever evolution to hunt with. They both group similarly. a little over an inch at 100 yards. I have killed 6 deer and 8 wild hogs with my 45-70 and it is the only rifle I have used since I bought it. The Winchester ammo came with the gun. The guy I bought it from had crept up on the scope and got hit in the eyebrow by the scope and was afraid of the gun. I bought is scoped wot a Redfield scope and two full boxes of Winchester ammo and one partial box of Remington ammo for $350.00.
