Got some more shooting and cleaning in today with the 33AX XP-100, with the 300 SMK's. Recoil was noticeably stronger. Shot a couple of 5-shot groups @ 100 yards with groups hovering around 1/2 inch (one group under while the other slightly over). Shooting off of a bench with a Harris BR bi-pod. Barrel is cleaning up good now, which is pleasing to see as well. Don't think this is a prairie dog rig, but I can't wait to get it set-up on steel. Recoil is about twice as much as my 7mm Dakota.
