Home Forums Hunting & Shooting Custom Rifles & Wildcats 6.8 SPC based wildcats??

I�ll admit to not being much for wildcats, but in my twisted mind, I�ve come up with a �need / niche.� (meaning: half rationalized excuse to pour even more money into my hobby). I was thinking that a CZ 527 is just begging for a 6.8spc based wildcat round with a .25 cal bullet...call it a 6.3spc? Basically a very short action .250 Savage. Would be great for moderate range deer and long range coyotes.

Now I know in the development of the 6.8spc, they went through several bullet sizes, but I haven�t heard if anyone has continued in that direction. To me, the 6.8 just doesn�t have enough sectional density for what I want to do. Does anyone know if there are any smith�s working with such a round? Developing a wildcat would be fun, but I have barely enough time to work with a wildcat, let alone develop one.

A 6.5 wildcat was developed by some of the posters at www.reloadbench.com , check that site.Rick.

if you neck it up to 30 you have a 30 remington. if you neck it down to 25 you have a 25 remington. although today with more modern steel and better cases you may be able to load them hotter than the originals to get better performance.

On the surface one would think...but that's not the case. The .25 Remington is a longer case and operates at much lower pressure.

The 6.8 SPC is based on the .30 Remington, just like the .25 Remington is.

i was thinkin' one of these in 25 in an AR shooting 100xxx would be just fine. also in a nula would be the cats meow.... maybe in a model 7 cdl also..

Wildcats have passed their prime. There may be an unfilled need, but every need I can think of has been filled by factory rounds or previously developed wildcats (e.g. 338-06 A-Square). What's left other than the dreams of their creators. It's fun to develop new rounds, but why develop the same rounds as previous developers?

Correction, 30 Carbine based shell. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />

i left it as a 6.8 and put it in a left handed mini mauser for my 10 year old son. the metal is out being blued and we are finishing up a blue, he picked the color, laminated stock. i think there are some deer somewhere that may be in trouble soon.

the mini actions are not that overloaded with new stuff. if it wont fit under 2.8"oal then you are SOL.. the ar brings that to mind... low recoil sub 5# guns would be real nice. especially if you dont need the outright horsepower of the 308 <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />

new shooters would be quite happy also. hard to find a 4.5# 308 that doesn't kick..... a 5# package for a youth in a carbine would be really nice. killing power (and decent trajectory) for as far as you would want them taking a shot anyway..

sounds like fun anyway.......... wonder what a mini in TI, 18" tube and a kevlar stock would do?

Do I see a new project in the works for you??

Have a 6mm woa which is 6.8 necked to 6mm. With 85 tsx its a mini 243 basically. Of course its slower but it works great on deer out to 250 yards easily.
FWIW

Nope, Lee had it right, its based on the .30 Remington.

Hmmm...

Let's see:

The 6.8 SPC is the 6.8x43 in metric terms.

Necked up to .308, it is the .30 Remington, maybe improved a bit. That seems redundant.

Down to .257, it's the .25 Remington, again, maybe improved a bit. Again, a bit redundant.

At 6.5, it's 6.5x43. Almost exactly like the 6.5 TC/U (which is the .223 Remington - 5.56x45 - necked up to .264); which wouldn't make much sense to duplicate.

At 7mm, it's 7x43, and again, there's the 7 TC/U. <yawn>

At .243, it's the 6x43 (which would be the equivalent and redudant to, the 6x222 and the 6mm TC/U).

So, why bother with wildcatting a cartridge to get exactly the same thing you get with pre-existing cartridges, with reamers, ballistics, and known variables already out there?

Wait... I'm sorry, I was thinking logically again... I have to stop doing that...

Uh, too late, Counselor. The crime has been committed. Your Looney License will be suspended for a period not to exceed 30 days. You may shorten the sentence by making .38 Special cases out of .357 Magnum brass and removing 100 hairs from your own head and splitting them each lengthwise into at least four parts..

"why bother", indeed! Yer lucky ya didn't get the book thrown atcha! (Handbook of Cartridge Conversions)

Curiosity up. For those that have the book.

What is usuable case capacity of 6/222 and 6mm tcu

Thanks, Jeff

41 and 44 grains of water respectively. the 30 rem gets 63. the spc is a good bit shorter. that is all....

no projects for me right now. way to much work. to many irons out there right now anyway. i would like to do one someday just cause.....

Ahhh... NOW I understand...

The 6.8 case is that much larger than the 222/223 family.

Consider the neophyte loonie edjumacated and enlightened.

Wildcat on, as it is something new and different it would seem... <img src="/ubbthreads/images/graemlins/wink.gif" alt="" /> <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />

BTW - you can't revoke the license of a loonie in hot pursuit of .32 H&R Magnum S&W revolvers. Rule 76.1(A)(III)(b), sub-paragraph 9... <img src="/ubbthreads/images/graemlins/wink.gif" alt="" /> <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />

Nimrod,

If there was any truth to what you�re saying, then they could have made the 6.8spc from a .223 case. The .30 Rem case was chosen because of its intermediate diameter. Lengthwise, the .25 and .30 Remingtons are both 51mm in length; the 6.8spc is 43mm, so there is a difference in length. Pressure-wise, the 6.8spc operates at about 55Kpsi (IIRC) vs. 38Kpsi for the two Remingtons. I�m guessing here, but my though is that in the end, you would have something along the lines of a .223 length .250 Savage�Am I wrong here?

To me, the cartridge is useless if you can�t put it into something like a CZ 527. Otherwise, if you want a .250 Savage, then get a .250 Savage. I�m thinking about this as a fun project gun that will end up being a deer rifle for my daughter� Just another case of wanton looniness; there�s hardly ever a legitimate case for wildcatting.

See the post I put up RIGHT before yours.
