Not at all my dear Watson....

Buy some 6.5 Grendel small-base dies and throw a bunch of old .308 Win or 7.62 Lake City brass through the sizing die, trim (if you need to), and enjoy.

6.5 Grendel is a caliber I've been obsessed with for well over 10 years. Stays supersonic LONG beyond the .308 Win, and with Berger 140 VLD's should be quite nasty out to 1,200 yards on deer.

Re: AR10 - Buy or Build

Correction on that last; You can't make Grendel cases out of 308 Win; they're completely different head sizes. The Grendel could be made out of 7.62x39, but not the 7.62x51 (7.62 NATO). I think you may be confusing this with the 6.5x47, which shares the same .473" head diameter as the 308/7.62 NATO cartridges.

My thoughts are that the 24" BBL is more than a plenty as mine is heavy as hell. if I were doing it over I would go with a fluted barrel for weight loss. AJ

Dogdinger what did you pay for the LR260? Thats a sweet setup. Friend has one and as you said its SUB MOA with just about anything.

I have used many variations of the SR-25 or DPMS style 308 AR platforms in the last 20 years. These were mostly working "Battle Rifles". Most with field expedient mods to make it run for the conditions. Only in the past 5 years or so did I have ready access to all the bling that the internet offers.
My all around favorite for a factory or pre-built 308 rat gun is Mark Larue's 18" OBR- I outshot the bolt guns out to 1300 yrds. w/ factory Black Hills 175SMK's. It's light enough for occasional walks through the forest.
But, as I get older and wiser- lazier, weight and ergonomics are more important.

The FBI has been experimenting with faster twist barrels and lighter bonded rounds. Without giving up their secrets, 155gr bonded 308's are staying supersonic out past 1200yrds in faster rifling.

I currently use POF's 14.5" gas gun as my primary 308 precision gun when a bolt gun just won't do. It's light and can be carried around all day- and will keep up with most of its longer barreled cousins. I even use this when most are using M4 SPR's. I pull off the scope and mount a red dot or holographic site. Nobody notices until it goes bang.

Good Luck

Mike
Mike,
Couldnt agree more. Great platform with the short barrel. EOTECH and the mag out. Once the mag is in all bets are off and they know your cheating

Sorry, was speaking of factory ammo!

Re: AR10 - Buy or Build

jimbo,
I bought mine back during the panic after obamas reelection so I wont even say. I feel I paid a premium , but didn't get hosed. I have seen them for sale since then for a couple hundred less. the new trigger cost me 189 I think, but was well worth it. AJ

Kevin, you are correct, just saw this post. Yes, I had a brain fart and completely spaced...Yes, 7.62x39 is what I was referring to, but had it all ass-backwards in my head.

My appologies for the misinformation before.
