First shots: Mauser 1871-84 mfg 1888

[Dutchman]

First time shooting this rifle. Did a small number loaded with RCBS 380 gr RN .446" loaded with 12 grs Unique. Wasn't a powder-puff load. (and no filler).

I had modified Starline .45-90 brass with the rim swaged back to make a wider headspace and they functioned perfectly. I was given two boxes of the Bell Mauser Base and there are apparently two different headstamps but both functioned perfectly. I was watching mostly for protruding primers after firing. The fired primers were perfectly flush with the casehead. And in inspecting the edges of the primer and the firing pin indent all areas failed to show any excess pressure at all. I was pleased with the appearance of the primers. I was bustin' dirtclods at 200 yds with the old krautvapen. Its a heavy dang rifle!

From what I see from the primers your load is relatively low pressure and perfect for that old girl. Absolutely no need for anything hotter so have fun!

If you want to tune for accuracy I would Start there and only go lower.


Interesting on swaging the rim to add to headspace. First time I heard of that.

Thank you for the info. I've got 20 Bertram cases and 370g flat nose bullets sitting on the back burner for maybe a decade. Just never got around to doing anything with a South American, shortened 71/84 "carbine" with a perfect bore. I think it was supposedly Columbian police issue maybe? That's probably just importer make believe bologna. I like to buy bologna sandwiches, mustard, no mayo.
Considering using Buffalo Rifle (D060) with 45/70 starting data.
Thanks for the nudge to check the back of the cabinets.

Good for you! I've never fired mine, to my everlasting shame. It also has a mint bore, but somebody sanded the heck out of the wood, so it's not the collector gun it should be.

Hello Dutchman, have you been still using that load on this? I have an 1871 and may use your recommendation on the Unique. Also what did you use for a boolit and lube?

[Thumbcocker]

Good on you for letting the old girl speak again.

Those are fun! Probably the best military rifle in the world for a short span of about three years. Definitely my pick if I had to stumble around colonial Africa & didn't know if the enemy was on two legs or four.

I have a Karabiner 71 and a 71 rifle, they are a blast to shoot. I was wondering if you could post a pic or two of your rim swage process?

Buffalo has disappeared

There are a lot of good propellants that work great in the 71/84 The Lyman 446110 drops a 340gr boolit that is well suited for the 71/85 Reichspatrone rifle. I have used IMR 4198, 4759. 4227, & 5744 with great success. These powders are bulky and work better than Unique. Take it deer hunting! Use soft cast 1:25 boolits. Put Bambi in the freezer!

What he said above. Yours is a tight bore so the Lyman 446 may work better. I prefer the RCBS. You should be aware that the dies may have been made to size down for a .439 bullet as was /is a common mis-understanding. That's a lot of brass working that is not needed and will wear out your brass quick. Also check expander plug. have fun.

I thought this was a dead soft and paper patch game?
