I am looking to get into target shooting and some deer hunting out to about 600 yards with the extreme possibility to 1000 yards. I am trying to figure out a rifle to suit my needs. The possibilities are..... 1.) I have a Weatherby Vanguard in 300 Wby that I am considering having a heavy barrel installed, an after market trigger and a new stock. 2.)Purchace a Savage 12BVSS in 300 WSM. or 3.)Purchace a heavy barreled rifle in 308 Win like a Remington VLS or a Savage 10FP-LE2. Any suggestions would be appreciated!
