TREEDOG,
That is the same question that I asked him. " Are you sure it isn' t a .270 wsm, or maybe it was a 7mm STW" ? He said, " NO, it is a .270 STW, it was custom made" . I did a search on the internet and did find SOME info on this caliber, but not much. I will be going to Kentucky (where he lives) for opening day of bow (sept 6), then I will get a chance to see exactly what he is talking about.

The funny thing is, if it is actually a .270 STW, he is going to have some trouble finding ammo. He said he only has a few bullets left and he doesn' t reload. He bought the gun from another guy who had it custom made for him.
