Going hoggin (four legged) in a week down south and wanted to bring my handi rifle for one of the hunts. Going to work up some loads. I'm using benchmark powder and win primers, lake city brass. Starting low at 23grains and working up in .3 increments. Do These guys like jump? The handi doesnt seem to have much of a throat. Bullet is 55 gmx 1in 9 twist. Have only tried factory ammo and 62 fusions have grouped the best. Still about 1-3/4 at 100yds.
