I have a Remington 700 in 25/06 we have had for years. It probably has had thousands of rounds ran threw it. Still shoots well but not like it use to. Gotta a few questions. 1st...What calibers, besides a 25/06 can you change to? And which would you guys and galls reccommend me to get? Prob be a deer gun. Ranging from 0 to 600 yards. But might be a little small for deer at that ranges so might be a extreme long range shooter for coyotes instead. 2nd...What does it usually cost to have it rebarreled? And what all would you have done to the action? 3rd... Who would you recommend? And 4th...What brand of barrel would you go with?
