New to the forum but have read some great info thus far. Have a question pertaining to the weaver tactical 4x20-50. Just bought a new model 700 .308 and want to start shooting out to 700-1000 yds. Realistically this sysytem will be used for hunting deer at ranges 500-700. I'm a capable shooter but new to mils and shooting at that kind of distance. Also, have a model 7 7mm08. How well would that caliber hold up at a distance like that? 129 gr. rem. hp ammo for it. Thanks. Any input is appreciated.
