7.5X55 Swiss components?

I am thinking about buying a Swiss Schmith Rubin K31 rifle, but been looking for reloading components for it and it is very hard to find anything on this caliber. Where can you buy the brass and bullet for it? I haven't found a single source that actually has the bullet!!!! this 7.5 mm what is it exactly in inches? is it .295? and where can you find the bullet?

Thanks in advance for all the help. by the way if you also know a good source for buying a K31 rifle please let me know too. thanks alot.

Midway has the brass.

Maybe others do also, but this was just the first place I looked. The so called 7.5 mm Swiss actually fires .308 bullets and you can find a wide variety of them anywhere.

Dear Slayer, Did you try Graf & Sons at grafs.com ? They have a LEE die set for $25.39 part # LEE90767. The brass they have is from prvi partizan #ppu75X55 100rnds for $45.00. You can use a .308 bullet. I have found a small supply of K31 at my local Cabella`s store. They could probably locate one for you. AIM Surplus should have some. Hope this was of some help for you.

I have purchased the Privi ammo from Aim Surplus, just for the brass. The Privi factory ammo shoots pretty darn good. I use 168 and 155 Sierra's in my reloads with 4064. Lee dies from Midway. Seating depth is an issue with the K-31's. Experiment.

I reload and shoot 6 - K31's, 2 - 1911, 1 - K1911, 1 - 1998, and 1 - 1889 Swiss Schmidt Rubin rifles. The Prvi Partizan brass is good, but you can use .284 Win. brass in place, even with the slightly rebated rim. Just resize to .30 cal. and load. I have had -0- problems just running the .284 brasss through the Swiss full length resizing die and loading, no problems at all. And yes, .308 bullets are correct for the 7.5X55 Swiss. Be cautious of overall length. The K31 has a very short throat.

It's the same .308 diameter bullet used in loading .308 Win and 30-06.

Yup. Use standard .308 bullets. Beware of overall length. Lots of loads at www.swissrifles.com. See the ammunition section. When you reload, shooting the K-31 should cost no more than shooting a .308.

The load I use in my K-31:

Sierra or Speer 150gr. Soft point over
43gr. H335 in
.284Win Brass, resized.
Lit by a CCI large rifle magnum primer.

Took my first hog with that load in that rifle.

I have heard (from swissrifles) that the Sierra 175gr. SMK shoots very well in this rifle, but have never tried it.

This is an email from maybe 1990 from my Father an enquiry about the rifle and cartridge.
----------------------------------------------------------

Good morning, Vince. Thanks for the enquiry.
The k31 and it's mates, the 1911, k11, PE57 and the rare (in the US) zfk55 Swiss Sniper Rifle are a rarity in another category. A Military series of rifles rifles designed around a specific cartridge, projectile weight and profile for accuracy and performance. The projectile is a 175gr of the VLD type.

The intent of this cartridge/rifle mating was to hit a human in the kill zone at range and they performed as intended. Not many production rifles are capable of doing that. The very great majority of these rifles perform flawlessly.

Are there rifles that outperform it? Of course there are, but none of them are a standard military issue firearm designed around a dedicated production cartridge for that rifle.

P

----------------------------------------------------------------

These are a few links to some useful info.

--------------------------------------------------------------

Since this was archived quite a few years ago we now exclusively use the Berger VLD 175gr projectiles and mostly RE17 (Swiss made) powder. Our Brass is RUAG Swiss National Match brass made in Thun and headstamped "T". The brass from Graf's is great stuff too.
Before the Bergers we used Sierra 175 SMKS exclusively.

Hope this help you.

be careful with this caliber

I have one of these rifles, and although I absolutely love shooting it, it can be quite challenging to reload for. And I also believe that this caliber was actually chambered in two different sizes, a .304 and a .308.

For reloading and general info, take a look at this: http://www.surplusrifle.com/swissk31/index.asp Based on what was said in the reloading section, I bought Redding dies, though I see Hornady makes a specific K-31 die now. You can use .308 bullets. Graf's is out of Privi Partisan brass right now, but they have Privy ammo that you can use to collect brass. As for guns, they cost a little more here, but you can see the actual rifle that you are buying and they have a bunch: http://www.simpsonltd.com/ Click on Long Guns, then Military Rifles and then Swiss. Spend hours drooling over them.

tkcomer,

God bless you. I did go on that site you mentioned and did in fact drool over all those pretty close up pictures of beloved K31 rifles. God bless you, you made my day.

Robert l, find Guisan on this forum or at SwissRifles.com and email him. He should be able to help you out. And your approx $250 (or more)31 value may be about $75 less valuable without the mag.

Happy, plenty of Swiss misinformation still abounds. Of the .304" dia rumor, even old Big Lee's SwissRifles.com site ,along with others, has with a reference to .304" diameter bullets and corrosive primers in the GP-90 series of ammunitions and is guilty of the rumor propagation. The Swiss never used corrosive(perchlorate) primers. The word should have been erosive not corrosive. And they never had a .304" projectile for their ammo. Inaccurate caliper readings of Swiss projectiles while still in their case and inaccurate bore reading of a 3 grooved rifle 1889 barrel may also have helped to keep these flames smouldering.

a lot of local mom or pop shops may not have Swiss stuff(GP-11 is military, 7.5X55 made by Norma, Prvi Partizan, Wolf, Hornaday, others). Mail order or larger ammo retailers should be a better help. A K-31's mag. It is the only thing you will find to fit. Follow ZFK's first link. Click on The Swiss Rifles Message Board (top left of the page). Guisan will not be hard to find and he sells many things Swiss. You may even find a mag for sale in our/your Classified Ads section.Best

Midway has had the GP11 ammo for the k31 in the past. If you plan to handload for it Redding makes dies made specifically for the k31 chamber. I bought prvi brass from Midway. Norma makes it also but it is costly. If Midway doesn't have it check out Graf and Sons. The k31s are very accurate and easy to shoot. I am about to put a scout scope on mine which should make it even more accurate.

I have bought loaded Prvi stuff from AIM then reused the brass. The Prvi ammo shoots well.

Going to do my first reloads for my son's K-31 tomorrow, we'll be shooting at 600 yards on Saturday.

H4350, 175 grain SMK's, and Prvi (once-fired) brass.

tobnpr, Cool Beans as some say. You must have access to some private property or you're going to the Manatee range. 1000 yards and open sights is a gas. If you're not going to a private range or Manatee, where are you going, if you don't mind my asking? Hopefully, you'll be working up loads and looking for an accuracy sweet spot and not start with a single charge weight and expecting the best accuracy right off the get go or maybe you'll use some GP-11.
Robert l, Most 31s usually have mags and a number of older models sometimes don't have mags(11, 96, and 89s). Have you visually confirmed at SwissRifles that you indeed have a 31?
Best All

When I began handloading for my K31, the proper 7.5 Swiss brass was not available (2008-2009 timeframe, a lot of brass was in short supply). I bought a couple hundred .284Win and have used them ever since. Not a problem, as conversion is very simple. No problem with the Lee 7.5 Swiss dies - work fine in my K31.

One thing I have noticed when it comes to reloading for the K31 is improved accuracy when using bullets between 175 and 180 gr over the 150 gr. At least in my rifle. The original mil load was 176gr.
