I tried a few last night and 71-72 gr of RL-22 is too warm for my rifle.

72gr left extractor marks on the case. Sadly I knew better than starting at the max. I guess it was a good reminder.

What have been your COAL that has worked best?
I have read many articles regarding best length for Wby calibers freebore. Seems like most say to seat them short, because the TSX likes the jump. Is this true?
Thanks again for all of your advice and input.
