Own two Browning 71's in of course 348'win. Lately I've been having an ball shooting them and love the lines if the 71 carbine models I have.

Somewhere I was reading about the 348 improved and wondering if it's an worthy upgrade on the 71 model. I'm not so much eager about any performance gains but wondering if this is an good way to improve case life.

Maybe this is an big waste of time and effort and I'm just best off leaving that slick feeding tapered case the way it is? I'm not set on this but have just been knocking the idea around in my head. Any thoughts? Leave it alone and enjoy them or improve them?
