What are you gonnna rechamber to? Seems like something awesome and abusive to both the shooter and rifle? just a guess since you don't care about condition.
I been working on a wildcat myself - the .17/50BMGGood little long range varmint cartridge. I can go prairie dog hunting in South Dakota without leaving Washington. Velocities are showing up in the Mach 7-8 range. Takes a really slow powder, though. Right now I'm using ground up Kingsford Briquettes, but am probably going to work up a load using straight anthracite soon.

There are several versions out there 7mm Practical, 7mm Rouge, 7mm Valkeri to name a few. I had my reamer built to my specks as in my preference for body taper, neck length, shoulder angle etc. If my math is right I should be able to hold right with the 7mm Ultra magnum with a 180gr VLD, using close to 18grs less powder when it comes to Retumbo.
Thats a good read right there........2 inch at 1k.....sheesh.
Here's a reply I read on a forum concerning necking down large powder devouring cartridges, got a good laugh out of the reply." That's nothing. I once necked down a 105mm artillery case to .177 caliber. was firing those copperhead pellets at around the speed of light. they would disintegrate, go back in time, kill a dinosaur and then create a wormhole in the space time continuum through which I would then enter an alternate universe as Emperor Xaseilsn, master of all I surveyed.
