Double tapped a bowling pin in mid air at a match one time with a 6" 629. I somehow got into the habit of shoting the last pin twice to get it off the table faster (no idea why) and every one said holy crap. Wde tried to duplicate that for months.
I shot my bragging shot with a Remington M788 fitted with a Bushnell/Banner 4x scope fitted with a BDC. I was using Remington 150 grain Core Lokt. I was hunting on the prairies and only able to get within 450 yds. I got into the prone, snuggled up to the stock, dialed into 450 and gently squeezed on a 6 pointer mulie buck, 1 shot, heart shot! He went straight down, dead. I never started out hunting season unless I had fired a minimum of 200 rds in practice for that year.
