I have a BLR in 308. The longest shot I have practiced is 265 yards. My rifle is more than adiquate at this distance but I dont think with the trigger I would try it in the field. I think it is a good idea to get a trigger job before trying any long rsnge shooting. I have had my gun at every gun smith in my area and they look at is and say it cant be done. The suggestion about Neal Jones is a good one. It will save you a lot of time and heartache. Mine has been at the smiths for 2 months and I got a phone call saying he decided he cant do it. I have talked to Neil Jones and looked at his rep on the net, Mine will be going to him soon if he can finnish it by late Nov.
