Mauser 1871 bullets

As cast Go.....and I don't remember what they measure...lol. I think there's some on the shelf and I'll measure them. I think the groove was .446 on both barrels with the right barrel showing a bit larger, like .4465 or maybe .447, which isn't uncommon in an old double that's been used. I bought that rifle in the early 90's which was when I did the work so, details might be a bit foggy.

I have a Vierordt double in 8 X 65R Brenneke and a Merkel O/U in 8 X 60. Both their bores measure the same but, the Merkel is between the wars and the Vierordt carries proofs from just before WWI. The Vierordt is Czech.

Like them guns don’t you.

Your "stalking rifle" is a reworked '71? Original loads will work best, PP with generous lube cookie. I hate PP'ing. I use RCBS 44-370. It drops around .448" +/-. Groove dia is up around 451+. Any boolits that big will not chamber for me. C&H have dies I call correct in that they size and expand for a .446 ish boolit. Others may not. The Lyman 446 is OK, I think they changed it a tad and the new don't work so good. I think RCBS made a 43-370 as well that drops about .439. You could go with powder coating and give us a full report. best of luck

Pictures on first post. 25 inch barrel. Mannlicher features: pistol grip , triggers, checkering, rear sight, and bolt handle. Action bought commercially, no markings on receiver, crowns on bolt. Made in Austria into commercial big game stalking title. Bought as a unit and professionally modified. Excellent blue. Very good stock pristine bore. 1874 on receiver.

Hello again
I got my loading data from Cartridges of the World, and it does just fine.
The 4198 is close to factory velocity
The .446 bullet seals the bore and does not lead.
All is well

Well, it appears "Candles on the Cake" and years between doing something have taken their toll and for that I apologize. Almost everything I mentioned regarding dimensions should be disregarded....except group size. But, because of Go's questions I have a project!!!!!

Pal, I don’t think a .450 bullet will fit in case. But I’m gonna try too. Then I’m set up to paper patch to .443. And want to get a few bullets in the .448 range. Three solid ways to attack this. All of them with some success. I hope I can have accomplishment here. You must have had some kind of smarts to find a duplex load. What kind of data points to that? Never seen it coming.
My project looks pretty straight forward and all within my knowledge. But to break out of that box would be unbelievable. Thanks to you and uscra112 for lifting me up here. Thanks.

What size will fit in a fired case? That's what I'd use, just like I do with my Swiss Vetterli and Argentine rolling block. Either a grease groove bullet or a slick patched to that size, cast from pure or nearly so lead, loaded over a full charge of black powder should work fine. The bullets bump up to fit and shoot accurately. By using a bullet that fits the case you don't have to resize your cases or use any dies on them so they last a long time.

Oh boo lit grand master do you like annealing?

[Gobeyond]

Why not cast a boolit like for a 45-70 @ .460, lube it, then run it thru successive Lee size dies so as to arrive at a .454" sized boolit.

I’m going to size one down to .448 if I can. Any problems with that?

[Gobeyond]

You may run into the difficulty I had in that the necks are too narrow to chamber a large enough boolit! One solution is a "heeled" boolit.

Thanks for that link!

The bullet has lube grooves on the heel portion and I also tumble lube the as cast bullet.. I think I get leading due to the .440 diameter heel should have ordered that at .446 to .448 also provide a snug fit in the case. Also I have had good luck with H777 BP A2400 and 5744 powders

Thank you for your answer. Do you like lee a lox or some other better lube?

[Gobeyond]

For what it's worth: I pulled out one of my original Mauser rounds. The bullet mikes .443" over the patch. The lead itself will be smaller than that. The O.D. of the neck mikes .466".

I'm unwilling to pull down a round as these are collector items now.

Once again: These bullets are dead soft lead, swaged, not cast.Attachment 295330

Yah thanks this is how it’s intended to be. We finally got it.

Grand master - I just noticed that. Pretty funny eh? But annealing? Yes it it one of the more fun things you can do with your spare time in a dimly lit room. OK, really it's just one of those things in life you just gotta do so may as well get it over with. And it does make your cartridge cases work a whole lot better.

I agree a 100%. But does it make your brass live longer?

Yes. It doesn't crack. Pretty much lasts indefinitely.

How often do you anneal a case? Every two or three shots enough? I hope I anneal often enough but up to around 8-10 reloads I start losing some. Could be imperfect technique.

It depends on the cartridge. Modern high pressure cases get annealed every time so the shoulder bump is consistent. Black powder cases get it every 2-3 times so they will always seal the chamber. Starline cases get annealed before anything is done to them at all as they are too hard from the start.

Sorry no bade just picking your brain a bit. What do you think of Quality-Cartridge brass? I bought some, all I could find for 43 Mauser. Not the best pricing but waiting patiently for them. I just wrote to grafs for an update. They are not overdue yet.

From what I've seen it is good stuff. I had some 44-90 from them that I turned into 43 Spanish and it was top quality.

I don't see the 11.15 Mauser listed on their web site. If this is it:
