Question on reloading for 7PRC

[orange1948]

Here is first loading / firing (100 yds) with new ADG brass in new Seekins with 26" barrel. The fourth group (not pictured) results are: 65.3 gr. N560, 2,967 fps, ES 5, SD 2.8, and group 1.18". Looks promising.

Looks good. You still have 1 1/2gr of headroom, and it should tighten up over that of your Group 4. Mine did as I reached max with N565

Thanks for the "heads up". I'll do that.

Be cautious as you increase the juice.
