The ADG brass was a great call. Very consistent between all the loads and results.

Kenton (and anyone else) if I found a load that was good but wanted to try the large rifle primers instead of the magnum primers to see if I could reduce the standard deviation . Would I need to alter the powder charge at all being a smaller primer ? Or is it safe to just switch between the two on a load . Attachment 249916

@Bowhunta
Are you still using Retumbo? I was shooting my cousins 22” Tikka 7PRC this morning and 69gr of 2225 was no where near your speed.
