Our club sponsors at least 4 benchrest .22 shoots a year, but they aren't limited to $1,200guns with 36x scopes by any means. While there were 10 of them (Unlimited Class), there were also 10 Plinker Class entries, which are essentially bolt- or semi-auto actions with 'scopes up to 8x permitted. It's also OK to have the triggers tuned and bbls. bedded or free-floated, as the case may be. Ammo, however, is target variety (i.e., expensive) with Eley Tenex to Federal 900B and even Wolf Match Target making an appearance.
I shoot a Marlin heavy-bbl. bolt action (syn. stock) that wears a new BSA 2-7x scope (has had a trigger job), usually with Federal 900B ammo. (Some think Federal's quality control has fallen sharply and won't use their target ammo at all.) Anyay, since .22 bullets ARE Pb, I felt I could post this here: A perfect score in my class (Plinker) is 200-10x. I shot 200-7x and 200-5x, which took 1st place and tied with another shooter for second. I'm pleased to say this is the best I've ever shot in this event!
Btw, a perfect score in the Unlimited Class is 250-25x. I've seen 250-19x, but today's high score was 249-11x, which was shot by a friend of mine & Vly's.
