So I plan on building yet another AR of the DPMS .308 type. I already have a heavy 24 inch one for target shooting (15.5 lbs) but now I NEED one mainly for hunting so it needs to be not so heavy. I would also like to use this baby in AR15Barrels' long range shooting club if possible.
I was originally thinking of going with .308 in a 18.5 inch barrel but then I thought that it may not have optimal velocity to make it to 1K without having to drop a rediculous amount that would be beyond my scopes adjustment capabilities. After considering this, I thought about the .260 Remington in the same barrel length. Would the high BC 6.5mm bullets be pushed fast enough out of a 18.5 inch barrel to even make a noticable diffference at ranges betweek 800-1K yds?
What barrel length and caliber combination would create a happy medium for hunting and long range shooting without being too heavy? If it helps I will be using a LMT SOPMOD stock (most likely), Fulton lower, Fulton or DPMS A4 upper, and possibly a Daniel defense Lite Rail 12.0. Thanks
