NO specific weight here guys, your not going to make a carbon fiber stock and proof barrel set up on a sporter style stock lighter, less you go
to titanium receiver, now your inexpensive build just got expensive...but she's right around 7 lbs when I weighted it about a year ago...don't think she's put on any weight since then, LOL. As in the thread, 24" long barrel, Proof doesn't make a 20" or 22" .277 barrel blank back then when I purchased the barrel.
The 270 Win is a soft recoiling cartridge, so didn't see the need to put a threaded barrel end (re: brake) on it either, more work means more $$ passed on to you. I figure this set up with scope and a few rounds is gonna be about 8lbs and a few oz. If its too heavy, drink a few less Budweisers the night before...(sorry for my cynical humorous approach early in the morning guys, but I think Grouse gets it)
If your looking for a serious mountain rifle, I have a 6.5 SAUM already built, and a 25 SAUM on a Model 7 thats in the works that I'm thinking is going to be under 7 lbs..
