7.5 swiss brass


October 2, 2005, 08:02 PM
When is ANYONE going to get new 7.5 swiss brass in?

I know you can use 284 win brass, but I would rather not use those unless there is no other choice. I'm not in a great big hurry. I would like to use this rifle as a backup deer gun (next year).

So, who has the skinny on the brass???

Why the reluctance to use .284 Win? The stuff works fine. It beats waiting for someone to manufacture new brass.

A number of people have received word from Wolf that 7.5 would be introduced this year with reloadable brass cases. I just checked their website but no mention of 7.5.

When I need 7.5 brass, I just drive over to Cabelas and get a bag of .284. No waiting. Works just fine and I couldn't care less if it doesn't have the proper headstamp.......

If I go the .284 winchester route, which brand would you recommend. Lapua, Norma, Winchester, or something else?

I am leaning towards Winchester because it is much cheaper. But if you feel like the others would better suit my needs, please feel free to tell me why.

I use winchester .284 without any problems.

Go the .284 brass route. Resizing .284 to 7.5 swiss is no big deal, in fact if I put a piece of .284 brass on your shell holder and a fired piece of 7.5 swiss brass on your shell holder while you were blindfolded, you wouldn't be able to tell the difference. ;)

First time you resize the .284, it might be a good idea to use a little extra lube inside the neck. That's the only part of the case that changes much, stretching to .308. I resized 100 cases, got one split neck.

Use Imperial Sizing Wax. A tin goes a long way. I use Win brass. It's locally available and lasts for a good long time.

Anyone use the spray on type lube to get inside the case necks of the .284 before re-sizing them? If so, how does it work?

Spray-on lube worked pretty well for me. I split 3 necks out of 100 .284 Win cases. My K-31 has never had any brass but reformed .284 Win in it. I have only used Winchester brass. Works fine for me. One batch of cases has 4 firings, now. No sign of wear.

I've got one lot of fifty Win 284 cases that's been loaded six times with no splits and no signs of trouble. First time sizing it, and every 3rd time after, I anneal the case necks. I use Hornady Unique case lube, and lube the inside of the neck using either a case neck brush or a patch on a short cleaning rod.

Thanks guys. I just ordered a hundred pieces of Winchester brass from Cabelas. I don't have any rifle that I can mistake .284 for anyhow, so the headstamp shouldn't matter too much.

Mistake? Easy to do. I put a couple of .308 rounds in my K31 by mistake. They shot good, the brass held together, and it was as accurate as the "real" stuff. But when I looked at the spent brass, it was shaped real funny.

I'm trying to be more careful now. :)

My other bolt gun is a .375 H&H. I doubt even I could mix up the 7.5 Swiss with a .284 headstamp and .375 H&H on the range.

I would really like to learn how to do this but I am totally new to reloading. Is there a special tool you need to resize the .284 Win brass? I was going to buy a set of 2 dies for 7.5 Swiss from MidwayUSA with other supplies (including a hand press), should I get that or a different die? Or is there more I need?

October 12, 2005, 08:02 PM
I've never used a hand press (lee type I think you a talking about) but I would think that it would not be conducive to case forming. The .284 to 7.5 is not a difficult job, but you'll be better off with a table mount style press. If you are trying to save cost, I believe Lee makes a really inexpensive "O" or "D" style press that will suit you well.

From the sites I've looked at it seem the .284 Win brass is almost as expensive as GP11 itself. I know you can use it a few times but that seems high.

No. I have the standard 7.5x55Swiss RCBS die set. The sizing die takes care of the resizing. There's not much resizing, mostly stretching the bullet opening from .284 to .308.

Besides, making the opening go from about .284"(7mm) to .30", you'll also be pushing the shoulder back at least .010" or more likely .020". Resetting the shoulder or failure to do so is probably the most common problem encountered when reforming the 284 brass to 7.5XSwiss. You will be reforming not resizing brass. A common problem does occur frequently when setting the OAL for a K-31. If one uses OAL info from load manuals that have no specific K-31 data, then their data reflects a longer throat for older Swiss actions. Do not try to set OAL's at 3 plus inches in the K-31's. It generally won't work. With exceptions, most likely K-31 OAL's will be in the 2.8 to 2.9" range. If by hand press, you mean hand held press as opposed to a mounted bench type press of some kind, you may have difficulty refoming the brass. Best-o-Luck

It doesn't say whether or not it's in stock, but worth checking into....

Huntington's out of Oroville, CA list them in the last catalog they sent me. Showed them @ $77.00 per hundred. I don't have a Swiss so haven't checked to see if in stock. Brand is Norma.

Sorry for the duplicate; didn't read the post above mine. Jon

Graf's has them back in stock. Placed my order the other day.

October 21, 2005, 10:49 PM
Thanks for the heads-up.

I just made my order.

You should check out Graf's Reloading in either Mexico or St Charles, Missouri. The 7.5 Swiss has the Graf headstamp. Price is right at $28 a hundred - which is about the price of standard US brass. I've been very satisfied with the brass. Probably from Eastern Europe, but the price is right.

November 11, 2005, 11:02 PM
just checked the Grafs web page 7.5 swiss is now in stock

Graf and Sons has a new brass, I just recieved 100 cases.

November 18, 2005, 04:46 AM
This is a first rate rifle and is one of the most accurate rilfles I have ever shot mine shoots two inch groups at 300 meters, more than suitable for a back up gun I use mine as a primary gun and wolud not be afraid to shoot anything with it.

January 24, 2006, 10:44 PM
What bullet do you use in the 7.5X55? I'm thinking of getting one of these!

January 24, 2006, 10:59 PM
I have tried 165g HPBT's without a lot of success, but I have only loaded 4-5 different recipes. I have had better success with 180g bullets, which everyone I know that shoots one told me to steer clear of. (These were both .308 Sierra bullets).

So I guess each rifle will be somewhat different. I believe the GP-100 is about 174g, so somewhere around there is a good place to start.

I have only used imr4064, but will probably try imr4895 in the future just because I have some on hand. I am only in the beginning stages of load development for this cartridge, but am leaning more towards the 180g bullet. Unfortunately, time has been a limiting factor in my pursuit of the perfect load :banghead:

FWIW, the folks at swissrifles.com seem partial to the 175gr. Sierra Matchking? Gameking? They say its closest to the profile and weight of GP11.

OTOH, I have great results with cheap 150gr bullets (Speer Hot-Cor) running around 2,550 fps. Its a lighter load, with somewhet lighter recoil. But very accurate. Sub-MOA when shot from the bench with my 2.5X scout scope.

I also run a "plinker" load using Speer's 110gr. "Plinker" bullet at just over 2,000fps. Same level as an M-1 Carbine. Same POI at 50 yards as my 150 gr. load has at 100 yards.

January 25, 2006, 10:02 PM
The 175 Matchking isn't a bad choice but the much more expensive 175 Berger VLD bullets come closest to matching the GP-11's nose profile. The 165-168gr bullet weights and IMR4064 seems to do well at 37 and 44 grains, YMMV. Sierra's data shows their Swiss accuracy load for the 180 bullets is with close to 46gr of H4350. The SwissRifles.com web site has a number of pet/accurate loads in the 165 to 180 weight ranges. Check out-Ammunition-Reloading Swiss Ammo-Pierre's.
