6.5 vs 6.8 hunting ranges

[LRRPF52]

When your wife or SO recoils at the price of an AR15, you simply explain to them that the beauty of it is that you can slowly acquire parts together on a budget, rather than swallowing a big ticket purchase all at once, and you can......bargain shop for quality components after a surplus in the market.

You can then custom-fit and accessorize the gun to how you want it.

I think the 30AR would be a perfect platform for a 6.5 platform for a 6.5mm Wildcat. Of course with another mythological name. Preferably something that just requires a shaping die. If it could push a 129gr SST at 2650 if you have a 510 yard hunting range from a 24in. Out of a 18in assuming a 20fps drop per inch it would have a 440yard hunting range. Then consider the Nosler LR 129gr and you'd be cooking with gas!! That would be a 515yard hunting range or about from an 18in assuming a 2530 mv. Who wouldn't like that?

The Nosler AB LR has an advertised expansion threshold of 1300fps, so with a 2500fps mv, it takes you out to 900yds, meaning it's really meant to be a long-range hunting projectile. The guy who showed his tests for it on the Nosler forum demonstrated that it does in fact open up rapidly, and has soft construction for maximum expansion.

. . . If you combined the 129gr Nosler Accubond LR with the 30 RAR case, that would give you a true long-range hunting, lightweight AR15.

The choice of a 30 bore was a strategic mistake for the RAR. If they had done 6.5mm, it would have really stirred the market up. . . .

A 6.5mm Grendel-AR15, all grown up! I'd have bought one.

Awe right good point. Make this Happen!!

Now that Remington has given us a robust AR-10 Bolt-Barrel Extension, in a lightweight AR-15 platform (Thank you, Remington) --- and we accept the single-stack magazine, as a trade-off --- how does a 6.5mm-30AR compare to a 6.5mm-270AR SPR?

That 270AR is going to be hard to beat with that high BC 150gr bullet. If woohoo gets his 2550fps from it likes hes predicting.

XcountryRider,

Dialing-in the 270AR SPR's expected 2550 fps Muzzle Velocity, with the Nosler 150-grain .277" diameter LR Accubond projectile (BC - 0.625), and using the 500-yard retained Velocity/Energy values, 1905 fps/1209 ft-lbs, as a parameter, I compared the 6.5mm 140-grain JLK VLD projectile (BC - 0.630) and the 6.5mm 144-grain Lapua Scenar projectile (BC - 0.636), at 500 yards.

Dialing-in 2625 fps Muzzle Velocity for the 140-grain JLK VLD resulted in 500-yard retained Velocity/Energy values of 1972 fps/1209 ft-lbs, while dialing-in 2585 fps Muzzle Velocity for the 144-grain Lapua Scenar resulted in 500-yard retained Velocity/Energy values of 1944 fps/1208 ft-lbs.

It will be interesting to see what velocities a 6.5mm-30AR and a 6.5mm-270AR SPR will produce!

Ingenuity: what would our sport-shooting world be without it?

Which would do better with the copper bullets? They will be a cali requirement in a few years.
