Egad! I did blocks and shims, with 2 hose clamps, and 40+ rounds of ammo to the local gunclub range for rough regulation, after using laser boresighters in the shop to get a size for the blocks at the muzzle and front sling swivel. The guys at the club gave me lots of room when they saw the hose clamps, and the 45-100 rounds. Found out why DRs cost so much. The setscrews at the muzzle in the photo are 4-40 allen, with 4 flats at the ends, so it's "click adjustable".
