has anyone ever necked up a 308 win.to 8mm?

Undoubtedly.  My Big Book of Wildcats is downstairs, but that one is so obvious I'm confident I don't need to look.

After looking around the internet, I'll say yes.  But 8mm-06 is more common due to the practice of converting Mauser rifles back when brass was hard to find.  I see one of these for sale fairly often.

Wildcat Cartridges has an article about a .33-.308 cartridge to shoot in a Winchester Model 88.

This is a strange one.  Why?

8mm unchambered barrels are not too common, and a 8mm chamber can't be cleaned up easily to 8mm-08 without setting the barrel back.  

It is easy to make 8mm brass from 30-06 if you need to.

Like pogo said, not much of a reason for this wildcat.

Anyone want to start a list of pointless wildcats or wildcats that don't fill a niche?

I'll start before AR jumps in with a pic of 10k of his favorite wildcat, the 9x39 Scorcher Supreme.




How about the 270 Savage.



300 Savage necked down to 270.



If you just gotta shoot 270 bullets out of your Savage M99.??

So what do you have AeroE?



Here is another, 357/44 Blain & Davis.

That one failed on revolvers as the bottle-necked case would expand back, binding the cylinder.

.300 Mashburn Short Magnum. I wonder if Art Mashburn ever got a chuckle about the irony of the Mash part of his name on these gus. This cartridge is ballistically identical to a .308 Norma, and close enough to dimensionally identical, which is the ultimate factory outcome of probably dozens of similar cartridges made by shortening .300 H&H or necking .338 cartridges in the late 40's and through the 50's. Thing is, Mashburn was a decade ahead of the factories. The rifle is pre War Model 70; sweet. Mashburn, Ackley, and Pope are the old time gun cranks I would have really liked to have met.



I have a convertible Blackhawk that a local gunsmith wants to rechamber to .357 Bain & Davis. I think I'd rather sell the gun.

Interesting idea.  Short-range heavy-hitter??

Plenty of 8mm barrels here: http://www.pac-nor.com/barrels/

Why not just go with a .338 Federal?

The first Centerfire gun I owned was a convertable blackhawk and I sent the 9mm cylinder off to Bain and Davis back in the late 70's when the work,shipping and a set of redding dies came to $85 if I remember.
Sort of a PITA to make cases and other than being something hardly anyone has seen or heard of it has basicly no use. I would guess I have Fireformed 40 cases and shot 40 or so full loads. I don't believe I have shot this gub with the 44/357 cylinder in twenty years . I haven't shot the blackhawh itself in 5 years.

Unless you are real bored I would recomend skipping this project!
