Finally got enough saccrificial boolits under my belt to get some decent enough to try at the range.
400gr cast lead bullets, SWC Keith style.
29gr of IMR4227 netted 1520fps avg vel and appr .5" @ 50.
Recoil was a gentle push.
Need to tune the load a little and stretch it to at least 100-200 yards but feel pretty confident with it for a whitetail load.
@ 200 yards will be hitting with appr 1k ft/lbs.
