Mauser M71 cavalry carbine at the range
Have now taken it to the range twice. There´s a choice of 50, 100 and 300 metres. Started at 50 and found that it shoots so high using the lowest flip-up sight setting that it´s impossible to test the rifle´s accuracy.
Can´t try it out on the 100 metre range as there´s a stiff financial penalty for damaging the target return mechanism. The 300 metre range might be the best option.
Re-loading is not much of a problem, now that I´ve got a sizer. Is neck sizing an option?
I´m using 446 grain bullets and intend to cast my own once they´re used up.
Think I´m now a bp convert.
First steps with an M1871 system
Patrick, three tips for all ex-service Mausers, of which an awful lot were zeroed for something like 300 meters.

Surely not a problem - you are presumably shooting way over the top, not down below?
1) Try holding the blade as low in the V as you can, while maintaining a reliably repeatable position. If you can get used to this, it will not only bring the POI down but also provide better centering of the aim.
2) Tack a second "Spiegel" (i.e the 26x26 cm target insert, for those who don't speak Mauser) below the black on the main target. This enables you to get some shots actually on the paper. Do this at 50m first, so that you can judge whether or not you are actually going to endanger the target return mechanism at 100m. My club was also very sceptical about BPCRs at first, and I had to demonstrate that I could get all shots in the black at 50m before they allowed me to use the 100m range.
3) Get an extra high K98k foresight blade from (for instance) Frankonia*. The Mauser foresight blade was never changed from start to finish. I have the K98k extra-high blades on the M1971, the M1871 Jaeger, the M1891 Argentine Engineer's Carbine, 1908 Brazil Mauser, and the K98 Israeli from FN in 7.62mm. One size fits all! It may look a bit odd on a carbine with foresight ears, but it brings the POI down into the black.

- Neck-sizing is the only option.
If you look at the fired cases you will probably see that the shoulder only bears a vague resemblance to that produced by the full-length sizing die. Neck and shoulder curvature and shoulder angle can be sufficiently different that, for instance, I have to use different case lots for the M1871 and the Jaeger. Full-length sizing really overworks the shoulder area, and will become expensive in cases.
As I have not yet discovered such a thing as an M1871 neck-sizer, I simply turn down the nut on the full-length sizer about 1/2 a turn.

*If you are likely ever to get another old Mauser, get more than one!
Nitro in one of the M71 family = no chance of zeroing the sights!

Yes, but... it's been altered to 7x57. Which knackers the collector value. So it might go for a reasonable price. Original M94 carbines in 6.5x55 seem to fetch shocking prices (for shooters, that is).

By heavens yes! - Patrick, are you shooting the M71 with nitro!!! - No wonder the shots are going up into the stratosphere.
BPCRs have a trajectory that is not a lot flatter than a well-fed muzzle-loader. That is to say, more like a howitzer than a .223.
Seriously, until you shoot the M71 carbine with BP there is no point in worrying about the POI or the grouping. Any nitro powder has a savage rate of onset compared with the kind of BP one needs for a BPCR.
That is bad news in a system with a single side-locking lug.
When you get your BP license, see that you get a small bottle of Swiss No. 4 and another of Swiss No. 3, as you will need to do some load experimentation. Swiss No. 4 is what I prefer for the long M71, but No. 3 may be better suited to the carbine length.

Uh, was that a question for Patrick or Patrick?
Whichever you meant, Patrick said it all. And I am not qualified to say anything about prices where you live, apart from the general rule of thumb that what you pay in dollars, we pay in euros !

Tall front sight blade in carbine
Patrick, here are some photos of the tall K98 blade in the Argentine Engineers Carbine.

The M71 carbine is probably very similar, and as you can see,
Attachment 33170
it may be necessary to file the ends of the dovetail to provide some left-right clearance for adjusting the windage.
