I am a bench rest and varmint shooter and belong to a local gun club as well as the NRA. 200, 300, and 600 yard matches are my regular shooting disciplines. I shoot .223, 6 BR, 6BRX, and 30BR.
UPDATE: This past winter season I have been shooting a 300 yard match monthly. I started to anneal after every firing. My scores are consistently higher! Is it all due to the annealing? I think not. But, I do believe it is part of the consistency package.
Recently, I shot in our club's 300 yard varmint match. Each relay consists of 5 score shots and one bonus which is a picture of a house fly (actual size!). I shot 2 out of 4 flies at 300 yards! Magnified photo below:
