RE: HandiRifles ?
I have not done much to the HandiRifles. They shot well right out of the box. I shoot a lot of Black Powder in the Buffalo Classic. I use Winchester brass because it holds a bit more powder than the rest. I shoot 500 Grain cast bullets in that one. I put in all the 2F that the case will hold, usually 68-70 grains. For plinking I shoot the 405 grain cast bullets with 13.0 grains of Unique and the WW Magnum primer. For Big game like moose and bears the 350 Grain Hornady RN is a great bullet. I load it to about 1850-1900 fps with IMR 3031.
AlthoughI have not used them to much yet, the 300 grain Nosler Partition should be a very good all around big game bullet for the 45-70. I also shoot a Marlin rifle in this caliber.
I use an OLD Redfield 2x7x32 scope on these rifles when I use a scope. I have had this scope for over 30 years and its been on so many rifles that I have lost count. It spent a few years on the 416 Rem Mag.
