I was around in the early days of NBRSA rimfire benchrest. The local guys went to the nationals and came back with four or five world records. Small groups and at least one aggregate. My best day I placed first in one class and second in the other shooting rimfire. Problem was the local shooters wouldn't settle down to one set of rules. I had a Suhl and a couple sporter/factory rifles, most pretty cheap. I still have an unfired Norinco and one with a few hundred rounds through it. I have a tuner somewhere but know how to tune without one too. What I got tired of was the constant search for ammo and the need of a half-dozen or so thousand dollar scopes or constantly changing the scopes from rifle to rifle. One week I needed a 10.5 pound gun, then a 10, a 9.5, I think they got as light as nine. Then they would jump back and forth between all of these.
One thing I chased just for grins at my home hundred yard range was shooting under an inch with the rimfire. I managed to shoot a five 5 shot group aggregate all under an inch at a hundred yards with my CZ sporter.
Even the best rimfire ammo in the world has a turd in it now and then which was another annoyance. I learned that a bad round will foul the barrel too so best to shoot the next round at something besides the target. Corrosive as hell but the old black powder rimfire ammo was more accurate and consistent than that of the eighties or nineties when I was shooting. Still plinking with that old federal match stuff I have had laying around forever.
Gale "Mac" MacMillan shot the group I am talking about.
