Put a 20" 1-24 to 1-32 twist 358 Winchester barrel on it and have the ultimate thicket rifle using a 190 - 250 gr cast FP bullet @ 2000 fps. The stock is plastic, so just slide that front action hole back a tad and epoxy it in place. Give it an over-all coat of Krylon OD paint.
That's a good idea, buddy, except for one thing. That stock ain't plastic. The Ultimate Sniper Stock is Choate Machine Tools interpretation of a stock originally designed by Major John Plaster. The damned thing is a fairly good stock, if you like that sort of thing. It's made out of some kind of hard plastic/fiberglass and it's got a full-length aluminum bedding block. And, it's heavy. I bet that stock weighs five pounds, all by itself.
You can click that picture to enlarge it, but there ain't no moving that hole without a machine shop in direct support. Besides, I don't like that style of stock. It's okay for the tactical guys, but I haven't worn camouflage to work in over a decade. I don't intend to start again anytime soon.
I'm thinking something more classic. Good wood, a blind magazine, a small fixed power scope, probably a Weaver K6. It may take me a year or more to build it, but this rifle is going to be light and handy. I did some checking today and I think that a .257 Roberts cartridge will fit in that magazine box.
That'll give the grandkids something to drool over.
