Ok, I’m having a huge dilemma on what gun I would need to shoot at 800 to 1000 yards with. The first thing I want is pin point accuracy, (of course with hand loads), second I want a bullet that not going to drift or drop to bad...here is what I’m looking at buying. My three choices are the Remington 700 Long Range Tactical in a 300 Win Mag, Remington 700 Police Edition in 308, or the Remington Model 700 SPS Varmint in a 243.All guns have the heavy barrel and I don't care about the stock cause I'm going with the XLR Industries Evolution stock. Any input would be helpful???
