If you were to design a wildcat, what would it be?

The 257 Kimber was what I based my cartridgè on.  It is virtually a clone but doesn't require any fire forming or a custom die.   Since then I've built a 22-204 ànd a 6mm-204.  The 204 case has slightly more capacity than the 223AI and with the 30 degree neçk feeds well.  The only fly back n the ointment is it is too long for à 527 or an AR.

So you have used 204 Ruger brass to reinvent the 222 Rem Mag?

ok, here is what I "Want"


I want a round that when fired from a weapon with an initial zero of 100 yards will only drop ~4.0 Mills at 900 yards!!!

The 204 Ruger case has the shoulder moved forward, the body slightly straightened and the shoulder chànged to 30 degrees, think 222 Rem Mag IMPROVED with no fireforming or custom dies.

I'd love to have a 25 WSM. Just guessing here but I bet it would be very similar to the 257 Weatherby but with less recoil and a belt-less case. I don't need another rifle but if someone would come out with a 25 WSM I'd find it hard to resist.

I too would like a .25 short mag.  Though I would like it based on the SAUM instead of the WSM.

Whats the biggest case size you can get  in the AR platform and have necked down to something like 6mm-6.5,243?

458 SOCOM fits an AR-15 platform.

How about a 6.5 - 458 SOCOM?   

There is your AR-15 deer/elk rifle!

If ya had enough nut sack, you could play catch with it!

When Kirby Allen was frist building me a rifle I was going to go with his 277 Allen Mag which is a 338 Lapua, improved to his shoulder, necked down to .277 but the supply of 169.5 Wildcat bullets ceased to exist so went with a 300AX for the, new then, 230 Bergers.

But, with Berger now offering a 170gr high BC 270 bullet, a 270-338 Lap. Imp. could be a lot more fun.

A few years ago I talked to Kirby about doing a joint venture on a 375-416Barrett with Kirby's proprietary taper and shoulder angle.  I thought it could be a fun project and give a sizable increase in velocity over the 375-408 CHEYTAC imp. stuff but he didn't think the increase would be substantial enough to warrant the expense.  I still think a 375-416 Barrett Improved would be pretty cool.  There was a guy over on long range hunting dot com that assembled the parts and pieces to build one but if I recall he developed health issues and it never progressed beyond him getting all the stuff to build it.

I checked out some potential ballistics, this is interesting!

.270 /378

.270 /378

Loads of powder and speed there!

I've also been looking at some 7mm options to try and get ballistics like these.

[kentrek]

That 195 bullet just doesn't know when to stop...no doubt the 7mm allen mag would be an incredible long range hunting rifle

 Beings I'm cheap I'd go for alil less powder and alil less brass and build 270 ultra and shoot as far as I ever wanted !!

I'm not sure how fast you could push the .270 ultra or allen? These potential ballistics look pretty interesting.
