I have been looking at and studying barrels and barrel manufacturers for a while now for an SPR build that I'm doing and I believe that I have chosen to use one of BHW barrels for this project. If all goes well I will be coming back for some future builds that I have in the works. But first I have a few questions that I'd be greatfull if anyone could help me with. As I stated before I am doing a SPR type build. I'm not looking to make it a Mk 12 spec but just a marksman rifle that shoots sub MOA to half MOA and capabilities to be accurate out to 400-600 yards. From what I've read and seen I believe BHW barrels are capable of this but I'd like to know your thoughts on that, thanks.

Oh and I will be using a 18 or 20" barrel for this haven't quite decided yet. Feel free to give you options on that also. Will be using this for manly shouting still and paper for fun and also some mid to long range friendly competitions that require some what fast shouting from targets ranging from 50 to 100 yards. Also may use for some coyotes are prayer dogs from time to time.

Caliber choice comes into play but a 20" 556 standard weight will carry the mail for you out to 600. I've spent a lot of time on my belly on 500 yard targets with BHW barrels. I have yet to find one that won't shoot under an MOA and most do half that with little effort. I've whacked many a PD with BHW's from 17-223 to 6X6.8. They did not enjoy the experience.

Greg Thanks for the response. Well when I first started this build I was planning on it been in 5.56/223 but I have recently had a growing interest in the 25X45 and the 6X45 and have kinda been thinking of going that way. Do like the interchangeability of the 5.56 round with my other ARs however. If stick with the 5.56 then be running 69g and 75g (77g also if the 1:8 likes it ok) for longer ranges mostly probably as well as 55g for just shouting around. I'm all ears with any thoughts

Versatility is good in our world. If I were staying with a 223 head sized case and wanted to move away from the basic 223 I would go with a 6X45 over the 25X45. Better ballistic BC for usable weights, way more bullet choices.
I've shot the 6X45 for over three decades and it has a warm spot in my heart. I've shot in 3Gun, sniper matches and F-Class out to 500 yards or so and won a ton of gold with it. Accuracy has never been a challenge with it. I just started shooting the 25X45 but see the limitation in bullets big the biggest issue for me personally.
If you want to go to a 6.8 based case there are a a great number of choices that perform extremely well with the same bullets ate higher speeds with more energy on target. Not hard to load for and a real hoot to shoot.

I first thought if I did go with one of the 223 case rounds it was definitely going to be the 25-45 but after reading some info and threads of yours and some others my thoughts have kinda gone toward the 6X45.
The 6.8 and other calibers based of that case seem interesting but required other changes to the platform and I kinda like keeping mine interchangeable. However I would like to learn more about them because I'm always wanting to learn anything and everything I can when comes to firearms...or really anything for that matter.
I do not know much about the 6.8 case based calibers others then they can reach out there and that they do not work with same parts as the .223. I know it needs different mags and bolt, I also imagine it needs a different lower as well. Is the upper still the same?

The only parts needed to convert to the 6.8 case or it's variants is a bolt and magazine. Your upper receiver, bolt carrier, firing pin etc. are all unchanged. Your lower will stay unchanged as well. Basically it's two parts and you have instant horse power!!!!!!

Now if I did go that way what would I be gainin with the 6.8 or 6X6.8 over the 6x45?

About 300 FPS with the 6X6.8 bullet for bullet. The 6.8 will be faster than the 6X45 but remember you are dealing with a round that bottom weight is just about maximum for the 6X45.

Oh right thanks Greg that's a good point! I hadn't really thought about the weight difference between the two, and how much more lead you could push down range with the X6.8. How bout accuracy and rang difference between the two? I'm sure the X6.8 has more range but at equal range witch is more accurate if ether? Thanks again for your time and all the help

6X6.8 all day long rules accuracy. Ritch's son killed an antelope at 646 yards with one. To some extent you have to set parameters. Deer, coyotes or PD's? Deer at reasonable ranges about the same if a guy can shoot. Prarie dogs and coyotes definitely are easier with the 6X6.8. Bullet choices are much better for the 6 MM as us the weight choice.
Personally I think the 6.8 just doesn't have the flexibility that gets my interest. The bore size is OK but the limitations in bullets that do well at 6.8 velocities really truncate its application IMHO.

Ok thanks that's some great info! Yea if I choose to go with the 6.8 case I'm pretty sure I'll go with the 6x6.8. Now one reason or a big reason I was looking at doing this build with the .223 or variant of it is because I wanted something that could be accurate at distance but also mild enough that could be used in CQB or 3 gun and similar. Is the 6x6.8 capable of this?

Its major use will be for longer ranges though

Is the 6x6.8 capable of this? Let just say with 25+ years of 3Gun under my belt the 6X6.8 is viable. It will be ideal if face with long range stuff. Obviously the recoil will be more than a 223 or 6X45 but not unduly so. It will not make MAJOR, for that the American 30 would get the call, but I would feel comfortable with it. Looking over in my corner I have one set up with a 3X9 and a dot ready to go. Just need to get off my butt and go. The only draw back is the lost brass in the operation but if you can buy the 1X Federal from LWRC it gets a lot better on the pocketbook. Greg

Greg I have really got to likin the 6x6.8 round from what ya'll have told me and other things that I have read up on since starting this conversation, and have really stated to lean that way to pretty much desidin that that's the way I would go. However you just brought up a good point and that's the brass...it's sure a lot easer and Cheaper to get .223 brass then 6.8. I can also go to a range and pick up brass for 223 all day and never see a 6.8. I sure like the extended rang and power of the 6x6.8 but if I want or need to go out past 5 or 600 I'd prob go to one of my bolt guns anyhow, probably.300 win mag. So although I agree the 6x6.8 sure seems to be a great round I believe I'll stick with a 223 of some sort
