I have a BC barrel on my Handi and love it, minus the fact that when I deer hunt I can move around very well always bumping into trees and such, that will be fixed when I get the shorter barrel and spin it off at 16.5".
But on to my handloads. I have been playing with light loads, since I cast my own bullets I have a life time supply at my finger tips. My normal cast bullet is 405gr or 500gr with a medium load so velocities are around 1200fps, I have to work hard at it to get a load that wont shoot good out of my barrel.
Well in my casting I cast a 255gr RNFP for my 45 ACP, I beagled the mold so it throws (out of round) around .459, then I size to .457 and I have a 45-70 bullet. Well I have been playing with hollow pointing my cast bullets on a drill press with a #2 center drill and a jig I made.
After I drilled my bullets I have a 240gr Hollow point for my 45-70, first thought "how fast can I get this thing cooking with accuracy. I had them close to 2500fps accuracy was ok about 4" at 50 yards off the bench, oh there is a 3-9 Redfield scope mounted on the barrel. I stopped at about 2500 because, IT HURT!!! recoil was to much to enjoy shooting it.
So I went back to middle of the road loads, right now I am about 1600fps and accuracy is one hole for 3 shots at 50 yards, very tight clover leaf. I am going to start working back up and try for accuracy and speed. I really want to see what this bullet will do to a deer or a coyote at around 2000fps.
I love my handi rifle
