I have a 16.1" 6.8 SPC Barrel with a 1:11" twist from Denny’s Guns and it shots great. I am actually going out tomorrow to test out the 4 different Hornady rounds. I can shoot around 1MOA with the Hornady 110 Gr. TAP (V-Max). It appears the 1:11" twist is the best twist available for the 110 and 115 Gr. ammo. I have mine set up more for precision:
As far as ammo, SSA makes some good ammo and if you are LEO or have an LEO friend, you can get the Hornady 6.8 TAP in either V-max or BTHP for $145 per 200 rounds, which includes shipping.
I have an LWRC 10.5" SRT and a Noveske barreled Stag 16". I also have a AAC M4-2000 in 6.8mm that I’m just waiting on the ATF to get my stamp back to me.
It has an ERShaw barrel and I assume it is a 1:9.5, 6 groove barrel. As soon as someone comes out with a 1:10-11, 4 groove, chrome-lined, carbine length, 4150 chromemoly barrel I plan on switching out. It should let me shoot the SSA combat loads without worry of pressure issues. I have been told by LWRC and SSA that my gun would probably handle it as is because of the short barrel length, but I don’t want to risk a pressure related failure in a NFA gun.
I’ve taken 2 deer so far with my 6.8. it works like a champ. I have a 16.1 recon brl, from Noveske. Its a 1/10 twist and it will shoot MOA easy. Grant @ G&R built it for me.
PRI and C-Products. PRI will be good to go out of the box.
Cproducts may be just fine, just make sure you do a functions check on the mag. If it doesn’t work, call Larry and he will get you some that do work. Simple and $25 less than the PRI.
I have one of Denny’s 12.5" WOA SS barrels and it shoots very tight groups out to 100 yards. It can probably shoot better, but I am not the best shot. Also, I prefer the CP mags over the PRI mags for two reasons. One, I don’t like shiny mags and two, the CP mags drop free whereas the PRI’s don’t. My CP mags functioned 100% out of the box as did the PRI’s.
I have been using CProducts 6.8mm mags for almost a year now and they have been 100% reliable. I sold off all my PRI mags for the reasons that ‘l2e’ mentioned.
Big fan of the 6.8spc. I use a PRI upper on a Colt lower. I’ve had 100% functioning. I have both PRI and CP mags and prefer CP. Both have fed reliably with no ftf. I use SSA and Hornady ammo. Heck…these days it cost less than comparable .243 or .308 factory ammo. Midway USA generally has a good selection/price for 6.8 ammo.
Sorry, Zumbo…I took 6 deer in 6 shots with the 6.8spc this past season.
Next season could be worse for the deer as my 12 y/o son has claimed rights to hunt with the 6.8
I’m really thinking the 6.8 could work for Antelope too… but I think the range would need to be 200 or less probably. I use a 25-06 normally and shoot them at 3-400 yards… so… maybe I should stick to that. We’ll see.
I used my 10.5" 6.8 for deer eradication on my friend’s tree nursury (we have a permit from the DNR). It dropped deer out to 225 yds, and it still fragmented.
With a 16" I would feel comfortable shooting antelopes much further.
