Hey Rex. I'm currently shooting 6.5 creedmoor and it's been very accurate out to 1200 yards. Now looking to stretch it out beyond 1600-1700 yards. I was considering the 7mm REM mag and was curious on your thoughts for this application. The rifle will be for hitting steel mainly. I have a PMII 5-25x56 to top it off so I'm covered on glass. Remington makes an off the shelf heavy barrel 700 'long range' in this caliber and I was looking into that.
