Hi Gents, being based off the same case is there a lot of work involved in this conversion beyond the rebarrel?

Or would a 45-70 on a 1895 be an easier/harder or more expensive route to take.

a friend did a 450 alaskan on the browning version of the 71, with the pistol grip -- 24" octagon barrel, matter finish .. of the few rifles i've seriously lusted for and then didn't build -

so, when it works, it works GREAT - but the 71 is a complex action, to my little mind

it makes a great rifle, can make it long barrel or other, and make it work ..

myself, i prefer the 71 over the 1895 for this

A 405 on a 95 is easy. I don't think the 95 will take a 45-70; if you want one of those, just get a Marlin, or 86 factory.
The 86 is a much older design, but will take the bigger stuff. The carrier and feed rails will need attention.

Speaking from having both a 450 AK and a 50 Alaskan-the "50" will require more internal action work
to the carrier and adjoining internals to allow
feeding of the larger case and cartridge.
Then, there may be the issue of accuracy.
Both of my prewar -71s in the 450 calibers are more accurate than the 50 AK turned out to be.

The "50" is now on Kodiak Island. Of course, for 50 yard shots or closer, it would do fine against the big bears. Much more effective than a bayonet.
