Some years back there was a nearly new 1895 at a local shop. Beautiful thing, and a gun I had always wanted to try out. Even came with a set of dies and some ammo and brass.
problem was, the rifle had the "rifle" crescent butt and was in .405 Win!
Now, that one is famous as TR's "Lion gun" but I can only think of a few rifles that would hurt one worse when fired, so I passed.
Converting one to .30-06 AI? why on earth would one bother??
First point, its going to seriously affect the resale value of the gun, but more importantly, the relatively small performance boost is not going to matter much, I wouldn't consider it worth the effort or expense.
If you're determined to have a .30-06AI levergun, go get one of the long action BLRs and convert that. The BLR uses a multiple lug rotating bolt that locks up at the front and is much better suited for high pressure rounds than the Win 95 is. Has a better shaped buttstock and is easily scoped, as well.
No, it doesn't have the "traditional" look but if you're interested in tradition, you wouldn't be wanting a .30-06AI, would you?
