Pretty much any lead 45/70 350 gr. bullet will do. Size .458/459.

Well, yeah. Guess I thought that was common knowledge.  My bad.

You are correct -- it is common knowledge. I just thought that it might be worth mentioning in case someone comes along who hadn't learned that yet.

Ok, I scored a Cimarron 1876 NWMP Carbine and want to shoot BP in the 45-75 cartridges. Since ammo is currently unobtainable, I have quested for an alternative. My online search for components has not been fruitful. Aside from powder ,primers and 20 cases (I bought the last 20) I have had no luck finding bullets. I have no experience casting my own. Any guidance on how to proceed is appreciated !
When considering a bullet, If you are going to run & cycle your 20 cartridges that you will handload through the magazine, You will want to take into account what your finished overall cartridge length needs to be to properly feed into the lifter from the magazine to function properly. To long or too short can tie up the action. Also consider that you most probably will want to have a bullet with a crimp groove to prevent bullet push back into to case when loading into the magazine ( although it can be done without a crimp groove). Take a look at Accurate Molds bullets designed for 45-75 wcf and note the distance from the crimp groove to the bullet meplate ( flat end of the nose ). That distance added to the case length will give you approx. COL ( cartridge overall length ) for that bullet design. You want a total length that approximates 45-75 wcf specs (approx. 2.25 )and will run in your rifle. If i recall correctly, the Accurate Molds bullet designs for 45-75 have a crimp groove to meplate distance of .36 - Many of the 45-70 bullets have a longer crimp groove to meplate distance that may tie up the action of your 45-75 if you were to use the crimp groove provided. Just some more you stuff to think about... Not that you needed any more to confuse you.

Thanks, it’s OK, if I didn’t love the variables of obsolete cartridges I’d spend my time shooting ball ammo in my Glock 19. I just wish I could score some loaded ammo for the ‘76 to get my feet wet. I’m a little surprised that Cimarron doesn’t sell the ammo themselves.

I've never bought ammo from Buffalo Arms (others here may have more to add), but even though it shows out of stock, it might be worth giving them a call. https://www.buffaloarms.com/45-75-winchester-black-powder-amobp4575win.html

I intend to. I recently picked up a Winchester 1880 loading tool for the caliber.

Square Butte,

RMC delivery times of late I can't answer for but they will get it to you.  I have purchased 45-75 brass from them in the past (couple years back last time) and can tell you it is worth the wait.  I do know they are swamped what with some other companies that make obsolete and semi-obsolete cases going out of business.  Last order I placed took a while to get but it made it.  Hope you have as good a luck with the cases as I have.  Options for getting cases made are getting slim these days.

P.B.

Thanks PB - I suspected it might be awhile. Good news is i have a little stash of Jamison which will keep me going until the RMC shows up. Glad you have had good luck with yours.
