Thought I'd post up a report.

I got a sample pack from a member here. And did some real serious load development last night.

I chose H4895, because I have plenty. Seated some 63 Sierras to fit in the magazine and tried them out this morning.

They did this at 200 yards.

I know I missed the quarter, but do you think by playing around with the seating depth, adding or subtracting a few grains it might work.
