I have the Katahdin 20 inch 460 w/aprature sight. With the Hornady 200 gr ammo it will almost cut cloverleafs with my old corrected vision at 75 yards. Recoil seems a little sharp and stout to me, but not unmanageable. I'm using the walnut stock, I'm sure the flex tech would help but the walnut just looks better to me. With 454 rounds my point of impact was about 10" lower at the same distance. Before I traded the 15 inch 460 for this 20 I shot a few 45 cowboy loads that were so high at 25 yards that the sight couldn't move far enough to correct. Haven't tried any 45 out of this 20 yet but there seems to recoil way less with the 454 rounds
