Well POW, seeings how nobody has tackled this one yet. Here's my thoughts. 1st I would think you would have to find a rifle that was chambered to handle the 307/356 round(s), and have it rebarreled. I don't believe just any "94" or 336 will work. But I'm not sure, I'll get back to that in a bit. 2nd, Unless you're set on a classic designed lever in a wildcat, I personally don't see much difference than the 250-3000 savage. The 25-307 most likely would faster, but by how much is the ?. A 250 sav. 99 can be bought for the price a barrel. If price is no object, then I would say a 250-07 would be a viable project. Reamers generally aren't a problem. Dies on the other hand, can be costly. More so, if they have never been done before. It don't make alot of sense, I've seen custom reamers made, for little more than standard. But, have of first time custom dies bringing 10 times as much. I think the die mfg'rs like soak'n us caters!! But it could be they need that much to recover a possible one time deal. But then again , 25-08 dies may work, I would have to look at that alittle more closely. Depends on how you want to cat the case. Thought 3, send the lever moderator (coug) a PM, asking him if this post would be OK on the LEVERS. If so, re-post it, or let me know if its OK and I'll move it over there. I'm just not up on the levers, although I'm toying with the idea of rebarreling a BLR to 338-06. That much I know will work.
