So this summer I'm looking into shooting competitively with a friend of mine. Seeing as that I'm on a budget and cant afford to buy or build a new weapon anytime soon I will be shooting my Marlin MR7 in a .270. So far I am able to shoot 1 MOA up to 400yds. I haven't shot much past that to have a good idea of my accuracy. My question to you guys; is the .270 a capable caliber up to say 8 or 900yds? I know a lot depends on the rifle and ammunition, as well as ambient conditions. I have been searching for awhile and have been unable to find much info regarding the .270 and shooting long range. I would really appreciate your input on the caliber as well as what I could do to my rifle to make it more accurate. Thanks in advance!
