I've only done that with "known barrel walkers", I shoot them first. I did have this done w/o shooting, a couple mos ago with a Kimber 84L .270....just because I had the time, then, boom, rifle Range closed down. Covid mess.
Thanks Mtn- good to know that! I always shoot rifles slow, especially during load work-up. I very, very seldom shoot more than a 3 shot group.
