Re: 300 RUM 700 Sendero, bdl or cdl help
Personally, I would look around for a good used Sendero. I picked mine up off gunbroker in the ball park you are talking with a Vias brake installed. I couldn't even tell it had been fired. There is one up for sale on this site right now, and no I don't know the person selling it.
The XCR II coating is great but any SS rifle is good to go in weather also. I've shot a couple light weight 300 Ultras and I will take the Sendero thank you. Also remember you are getting a quality stock with the Sendero. A little skim bedding and you are set. GunWerks LR TV show just took a stock Sendero II bedded the recoil lug, installed a trigger and scope, broke the barrel in, and shot under 1 MOA at 900 yards.
Also I wouldn't limit myself to just the RUM the 300 Win and 7 Rem are also good choices. Good Luck
