i have a 26" 300 win mag barrel that i would like to cut down a few inches. i am trying to save a little weight (alot of mountains up here) but i dont want to mess up ballistics or anything. i just wanted to know if anyone else has done,what the results have been,and how much they cut off.i see barrels all the time in the 20-22" range.any help would be greatly appreciated.thanks
