I already own and love my 6.5CM and I am not trying to compare these since they are really apples to oranges. I was building just a hunting light profile 300wsm but came across a more precision heavier profile barreled action and thought I pick it up to play around with. So I am wondering since I never really messed with the magnums what the effective range should be? Or better question what distance should I be able to take it out to comfortably?I will be shooting mostly 190-195's magazine fed out of a short action1:10 twist barrel. It arrives Monday so i haven't developed a load yet but previous owner said he tried h4350 w/208's and it didn't really like that setup
