I have a Handi Rifle chambered in 32 H&R Mag and I am trying to find a good load for it. I started with 85 gn XTP and a lot of different powders (2400, 4198, Blue Dot). I got it down to about a 2" group w/ velocities in the 1200 to 1500 fps range. I now want to use 100 gn Cast SWC. I tried Lil Gun, Blue Dot and H110 and all I got was a collection of holes in the target. All the loads were hotter than the suggested max for pistols. I would like to get a velocity of about 1200-1300 fps. I want to use this rifle for small game and short range varmits.
Any suggestion on where I should start on a load for this thing. My thoughts now are to use pistol powders and just load it like a hot pistol. Ideas?
