[Lumpy Grits]

Another run 90*f day with a little thicker paper (25% cotton eaton) and a different primer shows 1218 fps with 543 gr brooks patched to .450. Same Swiss 1 1/2 at 81.0 gr. Muzzle to first screen 10 ft.

Same set of batteries, or were these new/fresh ones?

I have changed batteries. Oehler says printer will start running slow when battery needs change?
Gunlaker, the load runs groups 1.5 to 2 moa at 370 yards with scope and sandbags. Groups 2 1/2 " higher than my gg bullets. This is not a paper patch chamber.
