I will be antelope hunting in eastern montana this fall and need a gun for it. I don't know a ton about guns and need some help. What would be a good gun for them that will reach out from 100 - 300 yards. I have a friend who is willing to sell me a remington model 700 25-06 with a nikon rangefinding scope for $600. Does this sound like it would be a good gun for some antelope and does the price seem reasonable. If not what else would be a good gun for a decent price for some antelope.
