Any Wildcatters Here?

[BarnesX.308]

Anyone come up with their own wildcat cartridges? I messed a round a little back in the day and necked up a 6.5 Carcano to 308 Cal. I don't have a rifle to shoot this in so it's really useless. Balistically it would be no better than a 300 Savage anyway. I was just bored, I guess :D.

I was wondering what I'd get if I necked my 300 Weatherby Magnum down to 7mm. It would sure be a flat shooting number. Although I don't really need that. It would just be cool to shoot a caliber I invented.

Anyone do it? Get the dies made? Have a rifle made?

I think that you would have something ballistically identical to the 7mm STW (shooting times westerner). The parent case for that is the 8mm Remington Magnum, which is just a tad longer than the Weatherby case, but not enough to make any real-world difference.

There are already hundreds and hundreds (if not thousands) of wildcat chamberings that it would be hard to come up with something that can do a better job than what already exists. The last real leap was when the PPC cartridges were first introduced, and that was done by a couple of guys from right here in North Jersey. For short range benchrest competition, those chamberings are still kings of the hill.

I was thinking about the 7mm STW but thought that the Weatherby case had less taper and a pushed-up, double radius shoulder that might give it maybe 5 grains more capacity. I don't know what the real world advantage would be. Maybe 50fps, I guess. Not worth the expense. More of a curiousity.:)

Have you ever looked into the Lazzeroni (sp?) cartridges? Some real fire-breathers there.

Even that might not be enough $$$ Scott. :eek::D:huh:

I remember when they first came out. The 308 is the Warbird, right? They have a long action and a short action. I think the Warbird is the long one. Back then, the 300 Weatherby was still king of the hill. Then this cartridge came out and had a good what, 200-300fps on the Weatherby? I looked at the rifles and they were like $3500 10 years ago. Ammo was outrageous and I don't think reloading dies were available yet. I decided to just keep saving for the 300 Weatherby. I'm happy with that. Not too many deer get up after I pop them with that. ;)


I was going through my magazines last night, looking for something to read in bed. I found an article on the 7mm STW, written by Layne Simpson himself. Isn't that funny?

I would like to see someone neck down a 24cal. (6M/M) using a
30.06.shell.
Think it would scream ! ! 100gr. bullet would really reach out there.:thup:

I think that would be pretty close to the 240 Weatherby. I think the 240 Weatherby is based on a belted 30-06 case. Velocities of a 100 grain bullet would be between 3350 and 3400 in a max handload.

[WoodsHunter]

Checking the reloading manual you are right. I didn't even think about Weatherby but that would be it...:thup:
Never had much to do with Weathery's products.

You can already load the 25-06 with 100 grainers or even 87s. I personally am trying to decide if I want to have a .25wsm built.

[WoodsHunter]

Yea know about te 25.06, just wanted to get a little smaller with the 6M/M. Wonder what the velocity would be with a 30.06 necked down to a 85grHPBT-6M/M. May hit the 4000fps mark.:huh:

I'll see what they have for the 85 grain bullet for the 240 Wby in my manual tomorrow. Should be similar.

How about necking down the 8mm Mag/7mm STW or 300 Weatherby case to .243? Throwing an 85 grain bullet out with that much powder would be a real screamer. Probably not the most efficient and hard on barrels, but who cares? :D

[WoodsHunter]

Be a mile downrange before you take pressure off the trigger.

[BarnesX.308]

In the Nosler manual, the fastest load for the 85 grain bullet is 3500. If you go down to the 70 grain bullet you can get 3750. I'm sure other manuals might be hotter but I think you're getting to the point of dimishing returns when you're burning that much powder behind a little bullet.

They had data for the 125gr Ballistic tip for the 300 Weatherby. That was close to 3700fps. That's pretty darn fast. Wonder what that would do to a ground hog?
