I've got a 16" heavy threaded barrel 455. Shot my first sniper match with it yesterday. I shot a 50 out of 60. Not the best I've shot in the past, but the wind was BAAAD!! When the wind was down, I was able to get a 9 out 10 at the 200 yard mark, and it was stacking bullets on top of each other on the sighter plate. I was shooting eley tenex, but it shoots just as well with Aguila Rifle Match.
