i have an eighties vintage Marlin 782 22wmr. depending on the ammo, AND how fresh it is, AND the temperature, it shoots (from a rest) as small as 0.846" 5 shot group @ 100 yards. while in the field however, I am not that good. i doubt very many of us are. with less than relatively new ammo, that the gun really likes, that is not nearly as good. if i average the ammo that i have, that is anywhere between 8-10 years old, to only a few months old, the gun shoots around 2-3" groups @ 100 yards. but to me, that is the thing about a 22 wrm. you can actually kill things reliably at 100 yards, and not feel bad that you may be just wounding it. my 22 lr's are all sighted @ 50 yards. but the mag is set @ 100. for what it is worth, my Marlin does not like the new "ultra lite" bullets of late. it likes the 40 grain winchester super x jhp's the best. so when actually hunting, i pick up a fresh box (and of course test) shortly before i actually go.
