Initial loads....Any and all feedback, insight, and opinions are welcomed. I don't claim to be an expert at anything so I'm always open to learn.
All loads are ADG Brass, CCI 250's, set .01" back.
Current round count after this testing is 74rnds.
H1000 under the Hornady 180's starting at 66.3gr, .3gr increments ending at 67.5gr.
Retumbo under Berger 190's starting at 66.8gr, .3gr increments ending at 68gr. Pressure signs at 68gr?
Going by the point of impact shift, I'm thinking 67gr H1000 under the 180's and 67.5gr Retumbo under the 190's for the next 125-150rnds letting the barrel settle in and stabilize. May play with seating depth a bit and see if they will tighten up.
Retumbo 190's 66.8-68gr front to back
H1000 180's 66.3-67.5gr front to back
Top left are the 180's, Top right are the 190's, Bottom left are sight in and Hornady box 180's, Bottom right are Fed 175's
Targets 1 and 2 of the H1000 180's was a whole ass thing. I couldn't see that the first shot hit dead center like it did and thought I saw it hit somewhere else and adjusted to that. Kinda have to disregard those two.
