I've very interested in this as well, specifically with factory ammo.

11.3" Wilson Combat?
I currently have a 16" Ruger bolt action and an 18" BHW barrel on an AR in 6.8. Also have a 9" 300blk SBR.
I have been thinking about selling the 18" barrel and building an 11.3" upper to use on my SBR and with my suppressor. Mainly for hunting predators, antelope, and mule deer.
Velocity numbers seem to be all over the place from the research I have done, numbers in the 300blk range to not much behind a 16" 6.8. Will the 11.3" push a 85-100gr fast enough to be a viable 250 yard hunting cartridge?
Also is the 11.3" up to the task accuracy wise?

Not sure about the Wilson Combat but from what I've read the 12.5" ARP is more than capable of pushing 90 to 100 grainers fast enough to use as a hunting rifle at 250. Not mention they are very accurate. You might want to check out the ammo and reloading forum. I've seen lots of good info there on shorter barrels. With the average 25fps drop per inch you would probably be looking at around 2600 to 2700 with 100 grainers out of a 12.5 inch ARP depending on how hot you're barrel likes the load and what's most accurate.
I feel the OP's pain, so often the answer to "tell me about the WC barrel" is "Dunno, but I have an ARP". (With due appreciation to KyScott for taking the time to share his experience!)
Since ARP can't sell me anything right now, I took the plunge and bought a WC 11.3 a few days ago. Just showed up about 10 minutes ago. If it shoots half has good as it looks I'll be ok!
I have a bunch of different kinds of ammo on the way as well. I'll post chrono data from it all within a couple weeks. I don't plan to reload and I have a 16" barrel coming, too, so I think the 11.3" length split the difference nicely between 12.5 and 10.
I'll post my results for all of it.

Keep me in mind when you get a chance to test it. I'm not in a hurry to get one put together but if it's better than what my 300blk is capable of I'll pursue it further.
I have hunted with 300blk in rifle length barrels with supers and liked my 6.8s better for killing animals. My current 9" 300blk is really just a toy for shooting subs suppressed. I don't have much interest in hunting with it with supers.
Wilson combat 11.3 is really appealing. The 12.5" would probably be just fine as well, if I could get my hands on one.

Will do, what you describe is exactly why I am getting into 6.8SPC. My 12.5" 300BLK has put many a deer in the freezer, as has my 7mm-08 MEGA MATEN, but I was looking for a round that would split the difference. (Yes, I could use the bolt actions that I have as well, but the AR just begs for tinkering!)
6.8SPC seems to be exactly what the doctor ordered. Another few hundreds fps, another couple hundred ft-lbs of energy. Looking at the ballistics it seems like 6.8 at 150-175 yards is equivalent to 300BLK point blank. Perfect. I hope this 11.3" barrel gives some good numbers with factory ammo. I was just looking it over, the machining is gorgeous.

I think you'll do just fine with the 11.3".
If you choose to follow the 1000 ft/lbs of energy at impact rule of thumb, 250yds may be the very far end of the ballistic capabilities for an 11.3", but I believe it will still do the job. You may want to look into the 120gr class of bullets for those longer ranges as they may retain a little more energy, especially the CBB 120gr MKZ if you reload or if/when they begin to offer loaded ammunition. The 105gr MKZ is showing to be quite the performer, too.

Thanks for the input.
I reload everything. So I'll look into those bullets. Maker bullets look interesting as well. I have used 110gr vmax and 110 pro hunters in the past on big game kills with my 18 & 20 inches guns.
250 yards was just an arbitrary yardage, mostly for predator hunting. I have killed upwards of 20 antelope with various rifles (the last 6 with a 22-250) in the last several years with two or three being over 250 yards. I have never shot a mule deer passed 120 yards.

For reference, I have a 10.5 LWRC that is very accurate with 110 vmax over reloader 7. My load runs 2340 fps and is moa at 300 yds no problem. I tested it into water jugs at 100 and 300 yds and recovered both bullets after pass through of 4 milk jugs. It behaves much more like a hunting bullet at the lower velocity with violent expansion to the canular ring, then mushrooms out.

11.3" Wilson Combat?
I have a Wilson combat 11.3. @100 yards suppressed. I also have an 12.5 arp, which I mainly hunt with. The setup I have the 12.5 seems more balanced.
Here some of my results for the 11.3

Looks very promising. Any idea on your velocity?
When you have a good bit of free time, read through this lengthy thread by Xman showing terminal performance from a large portion of the available bullets for the 6.8 at varying ranges/impact velocities and energy. It is very informing and goes to show exactly what alphasig said about the Vmax and it's terminal performance at lower velocities/energy as well as a good many other bullets.

Once you choose your bullet, there is quite a bit of load data reports here as well.

At 250+yds I think the 11.3" will do just fine for varmints/predators. And at the closer ranges for the mulies and pronghorn a good bullet should perform quite well. I have a 12.5" ARP which has done well for me recently on a wild pig at 236 yds. I know you're specifically asking about the 11.3", but I still think you'll get sufficient velocity for good terminal performance, especially with the MKZs and their reduced minimum opening velocity compared to other 6.8 bullets.
Good luck and let us know how it goes. I've got a 10.3" that I haven't gotten a chance to run velocity tests on but am curious to see your results with the 11.3".

When I did the stuff for the 11.3 I didn't have my chrony and haven't ran them through yet. But I can give you want I get with my 12.5 if you want those, which should get you then all park. Being only about a inch difference the fps probably be 50 fps less or so.Looks very promising. Any idea on your velocity?

Please do.

To the OP.... WC 11.3" is an awesome barrel and should give you what your looking for in performance. Can always do another upper with an ARP for fun later lol.

FWIW I had a 11.3 WC barrel and sold it then later bought a ARP 12.5 Don't regret buying the ARP but I do regret selling the WC. One of the most accurate barrels I ever had.
The difference between an 11.3" and 12.5" should be 50-60 fps.
I hunt deer and black bear with a 10.5"; most good 6.8 hunting bullets will expand out to 270-300 yards maximally.
Soft bonded/monolithic bullets like the CBBs or 95 TTSX will give you the most range.

Great info I appreciate it. I'm going to look into getting the 11.3" and dumping my 18".
I'm getting 2700 fps out my 11.3 willson barrel with 90 gr speers and 2200.
