Swiss K31 7.5x55
 

Hey Guys,

I just bought myself a new rifle, a K31. I shot this rifle at the shooting range and I just fell in love with it. What a nice trigger and the action was smooth and efficient.

Does anyone know A) Where can I get a copper brush for it and B) Where is the best place to get cheap ammo for it?

Thanks

Tom

I've never found a source of real cheap ammo for my 7.5x55.

Here are a few places to try:
Sportsman Guide
Natchez
Midway
Cabelas - Has Hornady SPs that shoot nicely out of my gun.
Graf & Sons

What kind of groups did you get? I saw one recently and think I would love one myself. Wonder if you can get a scope mount?

RE: Swiss K31 7.5x55
 

Brushes and jags are standard .30 caliber...same as your .30/06 or .308.

No cheap 7.5x55. Norma loads it, Graf/Hornady imports ammunition for it, and there is some Swiss ammunition available, too.

Look here for lot's of information about Swiss rilfes:http://www.gunboards.com/forums/forum.asp?FORUM_ID=37

I haven't shot mine yet so I don't know what kind of groups. I was able to get a group of about 2.5" with iron sights at 50 yds with the first 4 rounds I had ever shot out of another guys rifle. I also don't normally shoot irons.

Can I get some conscensus on the 30cal brush for this rifle? What is the conversion factor from mm to Cal? I figured it would be a brush between .27 and .30

That is a bit of a bummer about the lack of cheap ammo. I'm buying ammo at Dunhams for a $1 a round. Does it get cheaper from any of those other sources?

What are you guys who don't reload paying per round? How many rounds are you buying at a time?

Thanks

Tom

yep 308 or (7.62) is the same more or less as 7.5. If you reload for it you use 30 cal bullets. If you want futher confermation my hornady handbook list every bullet from 130 to 180 as .308.
hope this helps

Thanks for the replies. As long as the weather is good I'll be shooting this Saturday.

Yes you can get scope mounts for them. There are two different styles from what I understand.

Tom, despite being called a "7.5mm", the K31's bore diameter is .308", just like all U.S. so-called "30 caliber" cartridges! So any gun shop or even Walmart sporing goods dept., should have .30 caliber bore brushes.

The only way to get "cheap" ammo is to buy a bunch of 7.5mm Swiss cases with Boxer primer pocketss, and load it yourself. But as it uses standard .308" diameter bullets, any .30 caliber bullets can be used to load for it, including U.S. military M2 150-grain ball and 7.62X51 (308 WIN) 147-grain FMJBT bullets, which are often sold quite cheaply.

The cases aren't cheap, but you can use them practically forever, if you keep the loads at a reasonable level......

Eldeguello,

I'm slowly but surely coming around to the idea of re-loading. The issue is time. I don't watch tv so I don't have a hobby or something that I do where I just sit around and do nothing.

Eventually.

Thanks for the advice.

I was shooting one in az at my fathers place, What a treatto shoot. He got his ammo at Graf &sons. Not overly expensive. It was the first time my dad had taken it out since he bought it and we took it all the way back to the rams at 600m...... these rifles can shoot. Congrats and Enjoy!:)

RE: Swiss K31 7.5x55
 

The best ammo by far accuracy wise is the Swiss GP-11 ammo, its cheap when compared to commercial ammo, but is expensive for surplus ammo. Its worth the price if you just want match grade ammo. My handloads are about as good as GP-11 ammo, its just an unescapable fact that GP-11 ammo and the K-31 rifle were made for eachother.

You can easily reload for the K-31 by necking up 284 win brass to 30 caliber by simply lubing the cases up really well and running them through a 7.5x55 full length die. I do this very easily using RCBS dies, though RCBS dies need a bit of adjusting as they are more suited for reloading for a 1896 or 1911 swiss rifle. Pay careful attention to seating of the bullets as the throats on these rifles are very short, and the land to land dimension is closer to 0.299" than 0.300" as normally seen on 30 caliber rifles. Use .308 winchester reloading data even though the case capacity is very close to that of a 30-06.

I had a great time shooting my baby today at the range. Man is that rifle accurate. The trigger never gets old. I'm going to refinish the stock this weekend. What a great rifle.

If you are interested in keeping the finish as original as possible:
-Mix Zinsser orange shellac with boiled linseed oil 50:50
-steam the dents out of the stock.
-Rub a thin coat of the shellac/linseed oil emulsion on the stock and allow it to dry.

Hey Briman,

I decided to stain it to a color of my liking. This rifle is only about 70% so I'm using it as a project gun and a hunting gun. I've since found several websites where you can order up whatever condition you like. Down the road I may end up getting one above the 95% range even if I have to pay a few bucks. This is easily the best out of the box rifle I've ever shot. I can't say one bad thing about it.

hello--got 3 k-31 rifles- like them a lot--you can buy prvi partizan 7.5-55 ammo from[ aimsurplus.com ]for 10.95 per 20 rounds --new --174 grain --soft or hard point --brass cases--boxer primed--reloadable ---beautiful stuff-- as reasonable as 06--no problem

RE: Swiss K31 7.5x55
 

What Briman has told you is definitely spot on. GP-11 is the $h!t for the K-31. Definitely match-grade quality ammo. As mentioned, it is expensive though. The K-31's, in my opinion, is by far the most accurate military surplus rifles that you'll find today. The Swiss never produced any corrosive ammo, unlike most everyone else. Also, you may find a tag under the buttplate with the name, unit and location of the previous Swiss soldier that "owned" the rifle when they were still being issued. Pretty interesting.

RE: Swiss K31 7.5x55
 

It is amazing that we can get these rifles for the price. Of course, prices are creeping up, but it's still a great deal. Nice rifle, stat. You'll have a lot of fun with it.

I've been thinking of refinishing my stock, but I can't decide whether I want to take this into the woods next season. I'll probably just have to buy another one...

RE: Swiss K31 7.5x55
 

Tom, since the 7.5X55mm Swiss is a .30-caliber (.308" bullet), any brush that works with any U.S. .30-cal. cartridge, like the .30/'06 or .308" will work the same with the Swiss round.....
