6.8spc Rifle Options

[stchman]

Ruger makes a Mini-14 chambered in that caliber.

Only thing is I have met 3 people that have bought a 6.8SPC rifle and all three have said they wished they would not have bought it. I asked why and they said ammo is way too expensive. They said they had wished they had bought a .223 version instead.

Yeah, I think I'm just going to hold off on the 6.8spc thing for while. Ammo is scarce and expensive and I'm not financially prepared for another rifle platform right now. I already have 7.62X39, .308 and .30-06 and think I can do everything I need to do with those calibers. The 6.8spc will just add another caliber to my shopping list which I don't need right now either. The 7.62X39 is a very acceptable and capable round for most uses within 300yds for me.
I was dreaming of a one-rifle-do-it-all and thought the 6.8spc would be a good candidate. But, I think if I were to rely solely on one rifle, it'd be a .308, probably an M1A Scout with a red dot on it, aside from very long ranges, it'd do just about everything.

I am with you 100%.

If you already shoot 7.62x39 you may look into the 6.5 grendel as an alternative. You can make brass for it from 7.62x39. There is also a guy making reloads from steel casing 7.62x39 with plenty of success.

If you decide to spend close to 2K then I will suggest POF.

I am wanting to build/buy an upper for my Rock River carbine to hunt with. What barrel length would be best? I am wanting to stay as compact as possible. In East TN you rarely get a shot over 150 yds.

How about the 6mmAR or the 'improved' version the 6mmAR Turbo?
Essentially a 6.5 Grendel necked to 6mm.

The 30AR by Remington has seen people necking it to 6mm also...interesting.

Any barrel length will work for those distances. the 6.8 is a pretty efficient case and will do well with shorter barrels. The 6.5 likes longer barrels.

Robinson is very soon releasing "mini" and "micro" uppers for the XCR, which will take barrels as short as 9" and 7.5" respectively. Both will be chambered in 6.8, if you are looking for something that is super compact.

Remember that you wont get these velocities from heavy bullets. One thing I have noticed about 6.8 shooters is that they like to print their velocities, but not the bullet weights. It makes it hard for me to judge what kind of deer rile performance they offer. That said, even at 2,500 fps a 110 grain bullet is more than enough to kill any deer. If you can get around 2,800 fps with a 110 to 120 grain bullet then why use anything else? I just wish I knew what grain they are getting these amazing velocities with.

I've only got about 1200rds of 6.8 downrange and 9 hog kills under my belt so far, but so far I'm pretty impressed with this round.

As to bullet weight and velocity you can easily get an honest 2800fps+ with 85/90gr,2500-2600fps with 110gr and 2300-2350fps with 130gr out of a standard DPMS 16" bbl. Using 18" or 20" match grade barrels it's possible to increase these velocities by approx 10%.

The 110gr Barnes TTSX at 2500fps and the 130gr Nosler Accubond at 2300fps has killed every hog we've shot with it DRT. I even got full penetration on a 220# boar on a shoulder shot with the 110gr Barnes TTSX.

Mine shoots sub-inch with 110gr Sierra Pro Hunter, 110gr Barnes TTSX and 130gr Nosler Accubond.

In the hunting world I think it performs about like a 260 Rem with comparable bullet weights. Certainly plenty of punch for hogs and deer with decent shot placement.

A lot of good info on the 68forum

Could you please share your 130 accubond load?

I'm wondering what the options are on 6.8 rifles in general.

I know AR-15, Ruger Mini, and XCR. Are there any other platforms for the caliber?

If there aren't, what I think I'm going to do is just get the 6.8 conversion for my .223 XCR. It'll give me an excuse to start looking at a new .223 rifle. A very exceedingly WEAK excuse, but an excuse nonetheless.

Just build one it is so easy. You buy a kit and build the lower because it is cheaper to buy the upper than it is to build it. The how to is it www.ar15.com on a sticky. I do like the Armalite AR-10A4C better it is a little heavy but handles great because it is short. So you weight it and say no way,

Thanks,Keith

The 6.8 is a compromise. There are much better hunting rounds but they are not adaptable to the AR15 platform. That being said, the 6.8 is still a MUCH better round for hunting or shooting bad guys than the .223. If you study the numbers it comes in half way between the .223 and the .308 in power. It was invented for the same reason that the .40 S&W pistol round was, to get a more powerful round into an existing production firearm with as little modification as possible and it works.

 

[carnaby]

Not to mention that you can carry a 2x as much ammo as the .308 and about 1/2 the recoil, which is helpful when engaging multiple targets.

Have one and agree that the biggest negative is ammo cost. I'm still considering reloading. Otherwise, nice gun.
