All loads were .530 dia patched round ball with Black Mz, steel target placed at 47 yards with 4 shots with exception to the last target where I got a nice centered string, with one thrower to the left of center. After each group was shot, the target was painted over with aiming point painted. I was just aiming center on the target... point of reference was the open larger hole on the steel. My front blade sight was off just a bit and was corrected.

GPR was rested in a yoke mounted on a tripod, shot while sitting on a stool.

First group at 47 yards was spread and to the right using 45gr, second 50gr, third 55gr and last was 60gr charges

I was just looking for an accurate plinker load for my Lyman Great Plains Rifle.
