Charge Weight for Load Development (Tikka, 7 PRC, H1000) 

I’m loving it so far. Jam-20 is right at 2.530 and fits the factory mags without any issues. I’m doing seating depth now and will put something out when completed.

I haven’t actually measure that. The charge weight for my load had decent room left. Definitely was not compressed.

I anneal after every firing. I don’t anneal virgin brass.

I’m not sure what the exact diameter is but it’s the 7mm insert from Short Actions Customs.

@@gunsnoroses thanks, that explains the difference in jam measurement. I believe SAC puts a taper on their comparators.

I got 600 rounds through it so far and no issues. I check with a bore scope. I did drop the charge down and now am running around 2875 f/s. I haven’t experienced any accuracy issues with either.
