Most of my shooting is non big-game oriented ( other than the dangerous "big five" ground squirrel). Have several rifles and pistols to support that insanity. I have an urge to build-buy something in a old style single shot in the 2500-3000 FPS category. Looked at a lot of choices in the repro lines and some of the new varieties. What's your experience and education tell you to do if you were me. Thanks!
