I’m shooting those with Peterson brass in a 22” barrel. So far, my gun is liking 63.8gr and 0.040” jump.

Here’s a 10 shot group from the last time I was at the range. That one to the right was the 10th shot, and was all me and some mirage.

Came home and scrubbed the barrel. Going to reshoot and see what the gun likes best now- clean or fouled.

Quick work up last fall got me best accuracy at 69.5 gr h1000 in Petersen brass. Fine tuning this summer after barrel speed up, looks like I’ll end up around 69.2. Still doin some tuning, but having hard time finding cooler calm days lately.

Attached is bergers load data for the 175
