Just cut down a magnum case to 1,75" and reamed inside neck for 475 " bullets.
This is actually the 475" version of the 458 Whisper . Here in Italy such cartridges could be very useful for wild boar.This animal is often very big&bad and usually hunted at short ranges in the woods . Any suggestions?
I think that a rebarreled 450 Marlin rifle could handle this cartridge.Unfortunately 475" bullets are rarer than 458" ones and more expensive

Check out the 475 M3

Thanks for that link,very interesting.I will read it later very carefully.However I noticed that M3 wildcats are intended for the short Marlin action.
This would generate about the same power ( sufficient for the biggest wild boar anyway.The biggest my hunt squad has ever killed weighted 200 kg )in a much shorter and handy action

The power you want to generate with that case will be matched by the 475 M3 and you can do it in a smaller lighter gun. that case is too small for the 1895 unless you went to rifle bullet lengths or 475 turnbull bullets.
the problem you will have is pistol bullets that will hold together at higher speeds. Speer gold dots I have used on hogs at 2400 fps and they work great. all others might be too soft unless hard cast under 2200.

If you want a 1895 conversion look at the 475 Turnbull.

Oh,yes.I put a pistol bullet into the case because I haven't got any other spare 475" bullets at home ( except some lead bullets,like the one fitted into the 475 Maximum in the picture) . Heavier and harder bullets are a must in such a cartridge

I would look at the 475 Turnbull for a 1895 conversion

Have been the 470 and 475 Turnbull cartridges developed from 348 Winchester or 450 Alaskan brass?

other than being cool, it really won't offer any advantage over the 450 marlin.. and if you intend to use a marlin and rebarrel, why not do nearly the same thing.... shorten and ream, but with .458 bullets, and use HEAVY 458 bullets in the marlin?

think of a 1.75" case, inside reamed, and spitting a 500gr at 1500fps...

of course, there's nothing wrong with a 450 marlin and boars... unless you are the boar!

Sorry but the same comparison could be made between the 458 Lott and the 470 Capstick or the 450 Marlin and the 458 American...

Anyway,just wanted to make something "different" . It would be very difficult to have a rifle so chambered due the severe italian gun laws.

However,I 'd prefer the 458 American / 450 marlin loaded with heavy bullets instead of the turnbulls because cases like 348 Winchester,50 -110 Win and 450 Alaskan used to make turnbull ammo ( and the correct headstamped cases too ) are too far expensive,rare and difficult to obtain in Italy whereas belted magnum cases are tons around in every shooting range.Last but not least,if you have a gun chambered for the 458 winchester mag / Lott or for the 470 Capstick / Ackley or 475 Ackley you could use the shorter cartridges such as the 458 American or the 475 Belted in those rifles ( and using the same reloading dies too)

Pivi,
there is some validitity to you statement, but only between the 458lott and the 470 capstick, as the only difference between the 458x2" and the 450 marlin is the belt ..

what I was saying to you is that the problem you are trying to solve, heavy bullets in a lever gun, has already been solved, and your target donar gun could be made to do EXACTLY the same thing.

in fact, you could use that to prove the concept, and the ONLY thing you are "out" is some brass, as you wouldn't have to buy a chamber reamer, custom dies, new barrel, and gunsmithing .. just form up the brass the same way you thought about, but at .458, rather than .475.

you could inside ream some 450 marlin.. which MAY lead to brass failure, and would for the 470 if it did, for thinning the walls. I doubt it, but it could.

most 500gr bullets have the TOP of the crimp groove about .800 from the nose, so, if using the marlin/45/70 max OAL of 2.55, you could set your cases at 1.700, which would allow them to crimp. You might need to use another die to crimp, like the 45/70 resizer, due to it being shorter.

guys are getting 1800 FPS with 500gr hornadys in the 45/70.. which is about 150fps more than I had expected.

So, my suggestion is that you can prove this concept out, without spending a fortune, by scaling with a 450 marlin, cutup the same way
