True, the .270 isnt most folks choice for the relatively short distances you hunt, but has it worked well for you in the past? If it aint broke..
Your .270 doesnt vary much from my .308, and 90% of my hunting is the same sort of distances. I likewise selected a scope that would be best utilized like that... a 1.5x 5 variable. Too much magnification at close range can certainly be a drawback finding your game quickly in thick stuff.
I occaissionaly get an itch for a new gun, but what i have works, and works very well for quite some time now. It aint broken, so there isnt any fixin.
