Wildcat users?

Anyone of the board regularly use any wildcats these days? The one I'm most interested in is the 6x45 which is 223 brass necked up to take a 243 bullet. Seems like an ideal round for areas that are too hilly to allow for 400 or 500 yard shots even though the 243 Winchester serves quite nicely for that purpose. But still, less noise and to a lesser extent, less recoil - we need SOME reason for new cartridges.

The other wildcat I'm interested in is the 6x284 as an ultra long range rifle but its achievements and abilities.

Well, some are wildcats, some are just so obsolete I have to form brass for them.

Ultra-long range: 6.5-06, made from 7x64 Brenneke brass

6.5-.300 Weatherby Magnum being built on a Sako magnum action. Brass will be standard .300 Weatherby Magnum. Dunno about barrel life, I'll have to be rather careful, I'm sure.

7.62x45 Czech being made from .220 Swift or 6.5x54 Mannlicher brass

6.5x53R Dutch Mannlicher being made from .30-40 Krag brass

.32 Remington being made from .30 Remington brass, until I get that desktop lathe, then it'll come from standard .30-30 Winchester brass.

I used to make 7.62x25 Tokarev brass from .223 Remington. Thank Gawd Starline saw fit to make it a production item!

7mm TCU is another fun one to make brass for, if you weren't resourceful enough to grab a bunch of the excellent Federal brass when it came out. Just be careful and slow when necking up the little .223 round up to 7mm.

7mm Rimmed International can be made from resized and fireformed .30-30 Winchester, or for a better pressure curve, .375 Winchester.

I have a Barrel in 6X45 for an AR but I never used it too much. I did get a thousand rounds of "factory" ammo with the barrel and dies from the distributor. But it was rather anemic with a 75gr. Hornady at about 2600 or so.

I did get an 85 Speer BTSP to 2700.

Looking forward to the new 6.8mm Cart. for the M-4 for Spec. Ops. folks.

I routinely use 6.5-06 & .338-06 (as well as the .35 Whelen before it became a "legitimate" cartridge).

Fiddled with the .510 Wells Express for about a year then traded it off - the gun was just too heavy to be useful but the caliber was nifty. Traded it for a .45X3 1/4" Sharps - now there's a useful gun (tounge firmly planted in cheek:) )

Press on!

I have a Winchester lo-wall custom single shot in 22 K hornet. Shoots a 40 grain bullet about 300fps. Whats nice is you can shoot regular hornets in it also, no problem.

You might also want to check out the 6mm PPC. It is generally regarded as the most accurate cartridge in the world. Most bench resters use it. It may not even be classified as a wildcat anymore becuase I have seen brass already formed available to load for this caliber. I believe Sako even chambered a sporting rifle for it. It pretty well replaced the 6x45.

If your are getting interested in wildcat bench rest cartridges subscribe to the magazine called "Precision Shooting". You will find so many wildcat cartridges in that magazine you will have trouble keeping up with them all.

Never heard of this 6.8mm round for Spec Ops--please tell us everything you know about it.

6mm ackley current chambering for my varmint rifle. I have a digital camera, but its giving me a hard time at the moment so i can't post a pic of this rifle.

4000 fps you say, My favorite [out of my rifle only] 58 grain V-max over 47.5 grains of Varget, ignited with a CCI benchrest primer.

Seated .004 off the lands.

4000 fps - .4moa load out of my rifle.

3 inches of drop at 300 yards. Excellent crow & red fox load.[B]

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

Heard through the grapevine that certain Spec Ops units (specifically SEALS and DELTA) have made enough noise about the failures of the 5.56 to quickly incapacitate that there actually is a new round in development which pushes a 100-120 gr 6.8mm bullet at 2700 or so. Aactually, not being in the loop myself, I imagine it is already being tested, since a couple of people have seen factory loaded rounds.

Those who have seen it, surmize that it is the regular .223 case bumped up. While the Powley Computer (or modern versions) say that the ballistics are possible, I note that a 7mm TCU in a 14" Contender does not reach this level. Perhaps it is a slightly different case (maybe the size of the .30 Rem) or they are using a new powder technology like the Hornady "Light Magnum" line.

It should be interesting, but that is all I know for the moment.

Carry on and Happy New Year!

A person I work with that seems to know about new military stuff has mentioned this 6.8mm round as well. I thought he was just blowing smoke until now.

Hmmm...the current US martial cartridge necked to 6.8 mm (.277"more or less)...Jack O'Connor must have found a way to communicate from the other side,;)

as you can tell, I'm a K-Hornet guy too. I think you meant 3000, not 300 fps tho. Great cartridge!

has anyone ever heard of the .222 1/2? they mention it in the book point of impact, and i have found most of the gun info in that book to be accurate.

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

I don't have any personal experience with one but a benchrester explained to me that it was a term used for a .222 which has a chamber with a very tight neck so that one has to neck turn the brass to get it to chamber...

I think it sort of lost favor with the advent of the .22 and 6mm PPC cartridges.

Of course, the guy might have been blowing smoke for all I know - I always figured if the object was one hole in the paper you just shoot one time :)

Cheers,

I just inherited an unusual wildcat from a departed friend. Its a .357 mag pistol brass necked down to .17. Its a REAL Short Fat Magnum.

Hoping to find dies in his estate. Otherwise, life will get interesting...

Ross Seyfried had a couple of articles on that over the years. I don't have my old magazines indexed but I am pretty sure he had one while he was writing for Guns & Ammo and I think he did one in Handloader.

What gun is it chambered in?

Best regards,
