Alright guys I've been a lurker for quite awhile, but I finally decided I'd join up and pick your'alls brains. I've got a DPMS LR308 with a 16 inch barrel thats been sitting around not getting much use. I've wanted to turn it into a long range gun for awhile. I had been thinking I was going to rebarrel it in a different caliber, but wasn't sure what caliber to do. Most likely a .243 or .260. However recently I thought maybe I would just leave it how it is. I have all the reloading stuff for .308 and plenty of brass. Instead of spending money on the gun I thought I would order a good Leupold scope from the custom shop similar to a Greybull type. This would get me in the game quicker and start practicing. What say you guys? Is the 16 inch barrel sufficient to get to 700yds? Also if I stay with the .308 what loads you recommend. I would be using the gun for deer. I would like the ammo to be good on shots from right under a tree stand to my maximum effective range. From what I read you all like the 175 SMKs? Would the 175 be too heavy for the 16" barrel? I've been a barnes guy lately but I know they don't open up at the long ranges so thats out, neither do they have the BC.
