I have decided upon ordering a GAP rifle in the next couple of months (pending funds-selling several pistol's that are safe queens). Here is my question. For a starter long range precision rifle, would I be better served with the Crusader in 308 or should I go with something with better range and ballistics like the 300 WM? I am a hunter that owns just about every calliber for hunting just about every type of game in the world. But this gun will not be for hunting. It will be for shooting 500 to 600 yards on my family's ranch and eventually further. I plan to start reloading to make the most accurate bullets possible for the rifle. I am a bit of an extremist when it comes to my hobbies and do not want to end up wishing I had went with a 300 after getting into this. If I were to order a 300 would it make sense to upgrade to a surgeon action? Would it be worth the upgrade on the 308? Sorry for all the questions. I just want to do this right the first time. Thanks for your feedback.
