Hello all i have a rem 700 LA that i have been working with to make a good 500-1000 yrd gun. I have milled an aluminum chassis that will take AR style grips and an AR buffer tube type stock. I am split between what i should chamber it in... I'm thinking a 28"-30" med palma barrel. I would like to stay with the 6.5mm thinking the 260 rem or 6.5-06.. there are just so many choices. I have a 7mm rem mag to do my heavy hunting. what are your thoughts??
