My rifle currently is a customized Remington 700 Sendero in 7STW. I've done some upgrades to it. I've got roughly 1000 rounds through it over a 13 year span. Accuracy is 3/4" with the Berger 168's. I'm starting to think re-barrel, with round count and the wait for a new barrel. With the longer STW case it seems throating a new barrel would be difficult. My mag box is just a hair longer than 3.600" . Would going to a 7mag with the shorter case be a better way to go? I would probably go with a Heavy Varmint ,fluted and finished at 28".
