The early production .30-30 340 that I had shot well with iron sights and I didn't want to screw it up by drilling for a scope. I just lost, thru my fault, the opportunity to pick ua a 98% one that was drilled. I'm kicking myself over that.
I have a .222 one that shoots under 1" @ 100 yd. I was surprised by it's accuracy as I have had a few higher priced contemporaries of it that didn't shoot as well.
