Swiss K31


April 20, 2013, 11:08 AM

Any of you guys reload and hunt with one in stock condition using irons? Are the irons and action conductive for hunting/general purpose use?

It s a nice rig to have with the power similar to .308.

April 20, 2013, 11:44 AM
From what I read, it's actually more powerful than the .308 due to an increased case capacity. You get like an extra 100 FPS in 174 and 150 gr loads. Essentially it's 7.62x55 as you can use .30 cal bullets, which puts it in between 7.62x51 and 7.62x63 (30-06).

Any idea where to find published load data or is it all on the internet?

You re right. I have sighted mine with factory Hornady 174 gr SP at 100 yds on sandbag rest. It grouped 1.5 inch. The nice thing was , it hit an inch high with rear sight set at 100 meters. It practically was dead on perfect for what i need on closed in shots.

But the tightest groups were the GP11 surplus at 1.25 inch groups at 100 yds. These were all open sight benchrest shooting. I was speechless to say the least . The Swiss know how to make accurate rifles. I know i cannot duplicate those groups as that was three yrs ago but knowing the gun is capable is enough reassurance it s a keeper. Only accurate rifles are interesting as the saying goes, the K31 tops the list.

Have you taken yours hunting?

April 20, 2013, 12:33 PM
I like to hunt with mine. I was using Hornady ammo. I would get to where you can hit at 200 and you will be set. It works well. 165 gr. Ammo is what I used I think.

April 20, 2013, 12:44 PM
Correction, i checked the ammo box and it says, 165 gr BTSP. I got these way back from Sportsmanguide . I havent used mine yet in real hunting .

Looking forward to.

To think of it, the K 31s are like accurate sniper rifles but with open sights. Only limited by the shooter' s skills .

They make a good hunting rifle.

LOVE my K31. Has shot MOA before with GP11 ammo with irons when I do my part...that GP11 is some good stuff.

April 20, 2013, 05:35 PM
The GP11 ammo is worth getting when they show up. Its worth every round and every pull of the trigger.

April 20, 2013, 08:25 PM
For hunting, the Hornady soft points in 165 gr. are murder on deer.:D

I love mine. I was at the range with it today, in fact. Our range has steel from 200-600 yards. 400, it was no problem. 570, the wind was kicking them off a bit, and I had to compensate for not really being quite 600 and long for the 500 yard sight setting. 605, I had the wind doped, and smacked it a couple of times.

This was from prone, slinged in, unsupported. This rifle is a real shooter, with a great two stage trigger.

It is heavy, though. I doubt I'll be hunting with it here. We hike all day, sometimes, and put in some serious mileage to find animals. A six to seven pound rifle (or AR carbine in the woods) makes more sense for most areas around here. If I were stand hunting, I'd probably not own another rifle to hunt with. What would be the point? My K31 was built in 1934, and shoots the GP11 like custom loaded match ammo. I paid 80 bucks for it.

I have a hunting load for my K31, although I have not actually hunted with it yet. As far as accuracy goes, the K31 is amazingly accurate. I'd have to say the K31 runs neck and neck with my 1903A3 for shooting at 100 yards with open sights, and aging eyes!

April 21, 2013, 07:40 PM
Had a nice K31 a couple years ago but alas I'm a leftie the the straight pull didn't work out for me. Very well built rifles that can shot! Didn't want to spend the money to make it left hand drive. (

April 21, 2013, 08:00 PM
It was nice to read this thread. I was getting ready to sell mine and I don't even have the cosmoline off of it yet. I got it before I got disabled and it's a real chore to get to the range, now - and I no longer hunt... anything. But, it's good to hear that it shoots well so, I just might save it for the grandkids! Thanks all.:D

Have used mine for deer for a number of years. The longest one was a nice doe at 200 yards. The closest was 10 yards. With a rifle as accurate as the Swiss, if you do your job, it will put the bullet where it belongs. I use the 165 gr Hornady interlock stock number 3040 with 45gr of imr 4064. Very accurate in my rifle at just below 2600fps not a max load. YMMV As with all net loads, be sure to work up to them. Two years ago my SIL took his first deer with the K31.

I've killed a few hogs with my 1934 built K31, although it's really too long and heavy for the areas I generally hunt. All of my killing with the rifle has been with 150 grain Combined Technology Partition Gold bullets loaded over a healthy charge of Varget.

Keep in mind that most Reloading manuals will give overall lengths that are WAY too long. The short throat of the K31 is designed specifically for the very long ogive of the GP11 bullet. I don't have my data in front of me right now, so I can't give an actual length, but suffice it to say that my handloads looked a bit odd due to the small amount of bullet protruding from the case mouth. Another thing to keep in mind is that ammo loaded for best accuracy in one K31 may not fit into another. My experience has been that the newer the rifle, the shorter the throat. Ammo loaded for my 1934 Model won't chamber in my sons 1947 rifle and ammo that cycles perfectly in the 1947 won't fully enter the chamber of my 1952.
The only hunting projectile that I've loaded that looks "normal" is the Berger 168 grain VLD Hunting bullet.

This thread might be of interest, I was asking about the experience of other hunters with the Prvi Partizan 174 grain SP on deer.

April 21, 2013, 10:24 PM
I've got two of them and two cases of GP11. Nice guns for sure.....I took one down yesterday and I was impressed with the design of even little things like the shape of the wood screws.

April 22, 2013, 10:34 AM
I killed four deer this past season with a K31. It is now my primary deer gun. I am always impressed with the exit wounds, and the gun is spot on.

April 22, 2013, 11:20 AM
Do you guys think the supply has dried up and prices will rise?

Also, which do you guys prefer, walnut or beech? I've seen really nice examples of both, and the blonde beech ones look pretty cool. Walnut is always preferable, but in terms of build quality and construction, do the beech ones live up to hard use? Also are they significantly lighter in weight?

April 23, 2013, 12:17 AM
I don't know about beech, but according to Fred at freds14stocks, birch is far superior to walnut in every way, except possibly appearance.

April 23, 2013, 12:23 AM
I doubt we'll see any more imports. What's here is here. Samco Global has some examples with cracked stocks for a reasonable price. I have a Boyd's repro stock and handguard in walnut (85% inletted) but decided I'm going to just leave the pair I have as-is.

April 23, 2013, 12:52 AM
I have two with walnut stocks, and slings & bayonets for both. I like to shoot 'em, but I have so many guns that want to go play it's hard to get enough range time with any of them. Never hunted yet, and it won't likely be a K31 when I do. But I still love them! They're awesome rifles.

Anybody know how to date them by s/n?

April 23, 2013, 02:02 AM
Birch is strong, but what about beech? I don't they used birch stock on the K31?

April 23, 2013, 02:33 AM
AFAIK, it's birch on the K31's, not beech. Beech has the white "maggots" in the woodgrain, birch doesn't. I just prefer walnut myself.

I found this rifle from a private seller that wants $500 for it. It's probably the nicest example that I have seen. I believe the serial number puts it at 1953. The stock is not refinished and there are no gouges on the butt. Is this rifle worth the price? The metalwork and wood seem very good. There's no P on the serial number, any idea if this rifle was ex-police or unissued or anything like that?

April 24, 2013, 08:11 AM
No not 500
It's beech.

At least it is not son of beech...

Originally the gun cost more than that to manufacture but that is at the high end of the market. I bought an early 1950's K-31 with a scope for $350 last year, but the stock is not that clean. I don't believe it will ever have much collectors value as there are at least tens of thousands of them here already but if you want to own the cleanest K-31 I have seen and YOU don't think $500 is too much then by all means buy it. I know they sure make me accurate....

Found one just like it in really good shape about a year ago and consignment tag said $500...I thought way high...until in little letters on tag it said "With 800 rounds of ammo". Checked out ammo...440 of Prvi and 360 of GP11....SOLD. Good deal overall and superb shooter.

April 24, 2013, 11:23 AM
If you want one that clean, then no, it's not too high.

Last week purchased my first K31 for $300.00 , had been putting it off, but finally succumbed. SN puts it at 1941 production, butt is only moderately beaver chewed, metal bluing looks great and bore is mirror bright with sharp crisp rifling. Top of tang is stamped 53, which indicates it was rearsenaled that year. (possible was rebarreled at that time) Tag was still under butt plate and was issued to a air defense soldier born in 1934.

Does anyone shoot cast boolits in their K31? It is my intent to do so and it is my understanding the short throat of the K31 is will require a long ogive boolit similar in shape to the standard GP11.

April 24, 2013, 01:33 PM
I've seen a perfect condition beech K31 go for $800 on GB, so, $500 for one you get to check out up close is a fair deal. $300 seems to be the "floor" for one with a functional stock (less if you don't mind fixing a cracked stock). I paid $300/shipped for one and $335/shipped for another....both before $30 FFL fees. So, $500 out the door isn't outrageous at all (neither of mine are as nice as that one).

April 24, 2013, 05:04 PM
Wow !!!

These things have really gone way up in price. But then, what hasn't ?

I bought two of them about 10 years ago, both of them were under $100. I have shot one of them extensively. I used to compete in vintage rifle matches with it and was very successful. They are really great rifles.

I have handloaded for mine quite a bit and even used cast bullets at one point, but I really didn't know what I was doing and looking back, I was using a bullet that wasn't really appropriate for the gun. But, they worked pretty decent. I have also had a lot of fun with a cartridge adapter sort of thing with my K31.

I don't know if I would pay these kind of prices for one today, but based on how much guns in general cost these days, it might very well be worth it.

April 24, 2013, 09:21 PM
I've hunted with mine, but the sights get a little hard to see just before sun-down

April 24, 2013, 09:35 PM
Didn't take long to better GP11 on accuracy. I used pulled M2 ball bullets and 4064 or 3031 powder. I don't remember which. Just follow the reloading manual and you will do just fine.....chris3

April 24, 2013, 10:22 PM
Any rifle; is worth what you are willing to pay for it. If you think you'll never see one that nice again, in your lifetime, then it's worth it !! I payed too much for my mausers (so I thought) when I bought them; but I don't feel that way now, 10 years later.
I have put hundreds of rounds through all of them, and I am quite pleased with these guns that are from 1924, 1931-32, 1941,1948 & 1951.
Some are exceptional shooters and some aren't, they are all fun !!

@ rondog
This site's pretty good for dating K-31's by SN, it also includes yearly production totals.

@ dak0ta
Just to look at that $500 price from another perspective, back in the early to mid 70's, K-31's were over a thousand bucks a pop, IF you could even find one for sale.

I don't know about you, but I tend to buy milsurps mainly as shooting and hunting weapons with history generally coming in at third place. I've never consciously purchased a milsurp as an "investment", but I'm fairly certain that the "return" on my purchases over the years have probably exceeded the returns that I could have expected with most other investments.

While some people may feel that the 10's of thousands of K-31's imported will keep them from becoming "collectible", I tend to disagree. There were over SIX AND A HALF MILLION M1 carbines produced and at one time (IIRC), you could buy them for @ ten bucks apiece, check out the prices on them now...

I think the value of M-1 Carbines has more to do with the passing of the WWII Generation and the recognition of what that war represented to the modern world than with its value as a firearm. The gun grabber mentality of the left has also contributed to it but I do not believe the K-31 will ever approach the collectability status as the M-1 Carbine since it was not used by US troops, or for that matter, in combat.

May 4, 2013, 10:53 AM
Concur. That said, the K31 was sold for $79 back in the mid 2000's....those same batch of rifles imported by CAI go for $300-350 today.

I'd like to put the action from one of mine in a precision stock like a Manner's or something while keeping the other original.
