302 Whisper

[Rikky Lee]

Results with the faster pistol powder are showing promise. With no load data for H4227 I decided to load three loads; 13, 14, 15 grains to get a velocity trend pattern.

Starting with 13 grains produced an av velocity of 1145. 14 grains produced 87 fps more at 1232 fps. 15 grains was not tested.

The five shot group using 13 grains produced a 2 inch group which showed good promise.

Next loads will be 11.8, 12, and 12.2 grains I think.

Getting closer!
