    Optimal Charge Weight load development - Voodoo?

    Older thread but I have to ask. How well does this work for loading for a .308 AR-10? I have shot a 5 shot group out of a AK-47 .308 caliber that, using factory ammo, was pretty impressive given the firearm. My latest bunch of tests on a new LR 308 *DPMS 16" bbl. using IMR8208 XBR...

    7mm-08

    Anyone ever put a 16" barrel on an AR10, like the DPMS LR308? And at that length of barrel, would there be any advante over the 7mm-08 over the .243? Back in Nebraska where I am from, there are a lot of white tail and mule deer shot with a regular bolt action .243 rifle every year. Pluse they...

    Any comments on ER Shaw barrels?

    Re: Any comments on ER Shaw barrels? From what I've been told at E R Shaw, the 6.8 X 43 1:12 twist 5R barrel was not made by them. The mystery continues.

    Any comments on ER Shaw barrels?

    Re: Any comments on ER Shaw barrels? Well, you saw the marks it left on the brass. One in the middle is normal brass fired out of my Bison barrel. With a small screwdriver or any small rod,you can feel along the side of the chamber and actually "feel" that groove in the chamber. The...

    Any comments on ER Shaw barrels?

    Re: Any comments on ER Shaw barrels? If ER Shaw made the 6.8 x 43 barrel, with the 5R 1:12 twist rifling, it is odd that when they got done with the reaming of the chamber( whoever it was ) did not check the chamber for any signs of deformity. I suuppose there is a gauge that one could use...

    Any comments on ER Shaw barrels?

    Re: Any comments on ER Shaw barrels? They said to send it back. I just have to wait for the new stock to be delivered Nov 15th. FWIW, the target I shot with the 5R barrel was very good. I mounted the Bison Armament barrel back on an upper today and shot it to see how the firing pin, scope...

    Any comments on ER Shaw barrels?

    Re: Any comments on ER Shaw barrels? So, apparently the AR Stoner (brand) 6.8 x 43 5R barrel that MidwayUSA sells, is most likely from E R Shaw. What I had seemed to shoot well for the 6-7 shots I put though it and then noticed the ring around the brass from a deformity in the chamber...

    My Sig 522..sweet!!

    Re: My Sig 522..sweet!! Are you sure you don't have the bottom rail on backwards? They have a taper for a reason. It is to level it out because of the taper of the fore grip.

    Re: Today's State of the Art in 6.8 X 43 mm SPC I now have a Rock River Arms 16" barrel in 6.8 SPC II chamber, and an Adams Arms piston system. Recently with a hand load of Benchmark at 31.3 grain I pushed a 110 grain Sierra Spitzer to around 2760 average fps, and a nice group of around 3/8"...

    6.5 Creedmoor vs. 6.8 SPC

    Re: 6.5 Creedmoor vs. 6.8 SPC I'm from Nebraska, and I would rather buy the Hornady 6.5 Creedmoor ammo. I believe it to be a lot better than the Grendel for both close and far shooting. There is an AR out there handles the 6.5 Creedmoor. IIRC the Creedmoor is a bit shorter and can be...

    Today's State of the Art in 6.8 X 43 mm SPC

    Re: Today's State of the Art in 6.8 X 43 mm SPC From a hunting stand point, there are limitations as to bullet diameter that one can use on deer. In Nebraska, the criteria was ft/lb of energy at 100 yards. .223 was allowe, while .222 Remington was not. Some states care only about bullet...
