So you have the "possibility" to shoot past 300m, who has actually done it? No problem with a 308 bolt action rifle. Or is it just talk?
Not sure the context of this question?
Here on the prairies we shoot at distances further than you can see. I've hit a 55gal drum at 1500 yds and unsuccessfully tried to hit one at 2000 yds. I am currently putting together a shooting range out to 1 mile (1765 yds). I am lucky as I have access to private property but that isn't all that uncommon here on the prairies.
