right now i have a few .223's (bolt and AR), a 7mm rem mag and a .308 i don't need, but would like something a bit bigger in AR. as I see it I have some options. 1. buy an AR in .308 (LR308 or AR10) 2. buy a different AR upper I can put on my current lower, e.g. 6.5 grendel so for the heck of it i'm toying with the idea of getting rid of the 7mm mag and maybe picking up a 6.5 problem is i have a TON of 7mm mag reloading supplies, and I think (But could be wrong) that the 6.5 is still so new i'd be into it for considerably more in order to get setup. realistically i'll just punch paper and take out white tail deer, along with a few prairie dogs. i guess if I went for anything much larger i can hang onto the .308. for the most part i hunt in northern MN in the woods, i don't do much prairie hunting any more - but hope to and i'd kind of like to not have to reload umpteen calibers. but thought i'd ask around and see if anyone had a similar "dilemma" best regards.
