I owned a Winchester Mod. 94 trapper carbine chambered in .44 Magnum as my first deer rifle. I bought a box of Federal 240 grain HP. With the open sights I was able to pick a loonie off the top of a fence post at about 40 yrds. They are a great close range bush gun. Small twigs and leaves aren't going to deflect that bullet. I'd say just buy a box of factory ammo.
