does anybody know about some wildcats based om the x55 case? Have heard about wildcats on almost every possible case, but none at the x55 case! can somebody help me with my problem?

best regards, Peter

becuse i haven�t heard anything about it, i thougt it was that way... Alot of people use the 6.5x55 on all of our swedish animals, thats includes bear, moose, all kind of deers an so on! a very popular round here in sweden!

Have seen some cases that have been necked down to 6mm, and have had a 40degree sholder... but it is not comond, have just heard about it once, and that was from a benchrest guy.

Forster sells headspace guages for both cartridges and the SKAN version has a slightly longer dimension.

Now, given that this beast exists, how much better is it? I recall reading a couple of years ago an article by John Barsness on wildcats, and after analyzing various cartridges, he came to the conclusion that velocity increases (given same bbl length and same pressure) are around 1/4th the percentage increase in case capacity. So, if you increase case capacity by 10%, velocity will increase 2.5%. For a 2700fps cartridge, that works out to about 63fps potential, and that assumes the SKAN version allows 10% increase in case capacity.

Bottomline: Don't kid yourself and think you'll make big gains. If you need more velocity/power, pick a standard cartridge. JM2C.

You're OK with your Hornady die set for the 6.5 Swede/Swedish Mauser/Scandanavian. The cartridge I was talking about was the 6.5mm SKAN which is different.

Maybe someone else can chime in and confirm and/or set the record straight on the SKAN round.

Martindog

He lists a number of these with loads in Vol 1...

1) 6.5 X 55 BJ Ackley Improved. This was developed by Bob Jourdan. It gives a full 10% capacity increase.

2) The generic 6.5 X 55 AI.

Dave Manson makes reamers for both. Shawnie Tools has the generic reamer.

I think Hornady and Forster sell dies.

And noted GS George Vais has a few wildcats on it too. The 6 mm LiMe mentioned might have been the 6 mm L.U.R.H. - basically just a 6 BR reamer run deep and cases formed to fit. I know our buddy Stefan K. has a shortened (51 mm IIRC) 6.5 too (along with a L.U.R.H.).

Nope. It'd not supposed to be loaded in the old ones, but in the new ones: The Sauer rifle used by Scandinavian target shooters.

The SKAN is loaded hotter than a normal x55.

FWIW, I've never seen an old military or new commercial 6.5x55 that would not swallow 6.5 SKAN ammo.

Of course :-)
I own a 8 x 54 Krag-Jorgensen (8 x 54 Svensk omborrad Mauser), and then there is the 7 x 54 Finnish. Both are "semi-wildcats" in that they were once factory loaded.
A true wildcat is the Norvegian 6 x 55 (made by Tor Treider). The 9,3 x 55 has been speculated about in the Vapenjournalens Ladebok, so I suppose somebody has necked it up in the meantime, in a long dreary midsummer night :-).

The formerly named 8 x 54 is quite accurate. Its performance is about akin to the 8 x 57 JR or the 8 x 56 MS. I had mine loaded by DKT. Old Norma factory ammo can occasionally be found.

Thanks for the clarification. Just curious, how popular is the SKAN round over in Europe and do you have any idea how it compares to the .260 Remington (By the way, has the .260 rem caught on in Europe yet)? What kind of velocites are achievable with 140 grain match bullets and how long are the barrels you're using?

Thanx,

Martindog

The SKAN is chambered in the Sauer rifles only, therefore it is per se not common outside the target shooting scene.

It, of course, runs eights around the .260 velocitywise and accuracy is very good. It takes a few grains more powder then the .308-based cartridge.

thanks for all the replies!

But as is, the 6.5x55 is one of the BEST medium game rounds ever devised. Those long, slender bullets have high SDs/BCs and hold up extremely well while affording excellent penetration, even with "standard" bullets. All of my 6.5x55s prefer Re-22 and provide the best balance of velocity and accuracy with this propellant with bullets ranging from 95-140 grains.

Personatly I don't see any use for such a round, but..... gun nuts like us can do anything!

In my eyes, the .260 Rem - formerly a wildcat as 6,5-.308, I believe - is a candidate for the prize of the most superfluous factory cartridge ever (close second would be the 8mm Rem Mag). But to each his own toy :-)

Now don't hold anything back. Sugar coating will get you nowhere. Tell us how you really feel.
