So, I found BHW while doing research for my current long range (800yd) AR build. I have everything except the barrel and was leaning toward a 1-8, stainless SPR profile and shooting 75gr pills at 2750-2800.
Any reason to look at a 20" or a 1-7 twist? Are there any reviews on accuracy of the BHW SPR barrels?

So, I found BHW while doing research for my current long range (800yd) AR build. I have everything except the barrel and was leaning toward a 1-8, stainless SPR profile and shooting 75gr pills at 2750-2800. Any reason to look at a 20" or a 1-7 twist? Are there any reviews on accuracy of the BHW SPR barrels? The poly rifling is going to help almost 100 FPS in my experience from their other barrels. The 1:8 will handle your 75's and I would not hesitate to use it. BHW is doing me up a 1:8 24" for 1000 yard F-Class and other targets of opportunity and I have no fear that it won't do fine for me on the line. I haven't seen a direct review at this point but I've notice most of the guys I've been seeing with new BHW barrels across the net, and I am all over the net, are shooters and don't do a lot of writing on their results past how impressed they are on their first trip to the range and how fantastic the finishing is on the barrels. LR shooters are a small sub-set of the shooting world and I think only those that are less timid will attempt much past 300 yards. Laying down at 500+ and punching papers calls for good equipment and, that one thing that is almost innate, the workings between the ears. The learning curve of the ballistics and use of scopes, drop tables or straight irons is pretty challenging. No one lays down and puts 'em all in one hole the first trip or two. Humbling is the word I am looking for on this one. Go with the BHW barrel and you won't be disappointed. If I didn't believe in them I wouldn't have two on my rifles now with three more to go as a minimum. Greg

Welcom to the forum. Presicion long range AR are the sacred cows of the rifle World. Generally, people whom are planning an shooting anywhere past 600yds like to use barrels larger than 20". In my opinion, 20" is adequate for 800yards provided you do your part (wind estimation, trigger control, proper breathing, and natural point of aim).
For the bullet selection you specified 1:8" is all you'll need. I have a an 18" 1:7 and I wish I had found BHW before I purchased that barrel. I pruchased my first BHW barrel and haven't looked back ever since.
As for the SPR contour, the standard contour would be the thing to get.
Shoot straight.

Thanks for the reply Greg! I current shoot a standard M4 profile in 3 gun, and a 308 bolt gun in long range.... While I've been waiting (and waiting... and waiting) on my Form 4's to come back, I thought to myself "wouldn't a 223 long range rig be awesome with a can on it?". And here I am.... Now the decision on 18" or 20"......... so many choices

20" for the win. Velocity is the king when you put the accuracy with it. I want all my go juice when I shoot out yonder. YMMV Greg

I hope like the devil my 24" shoots good. I got the Bull 24" 5.56 ordered and planning on using it for 600 and 1000yd Fclass. But seeing as our 600Yd range got closed, ill have plenty of time to work up a load till we can find a new range and get the pits built.

Well by sheer coincidence I have a 24" bull barrel upper headed my way via RPG, Ritch Johnson, that should be here on Thursday. I just went to buy some bullets and they are out of the 80 Sierras so it is the 75 AMAX for the first long range poke. I'll do some initial work with the 69 Sierras but that will just be for familiarization. Scheduled to shoot an 500 yard F-Class on the 22 nd. here and I am excited. I'll be using my 6X45 BHW for that go around. Keep us posted and I'll chime in as I get some data on the new barrel performance. Greg

IIRC I've sen some F-Class guns in England using a can. They are a tad different there though!! Just like muzzle brakes are not allowed in real F-Class matches the local clubs are letting them shoot. They would rather a competitor be on the line than a guy not showing up at all. I discussed that with the local match director last week and he allowed as how they wanted anyone they could get to come to a match and as the person got hooked they would see the light. Greg

Its the same here, pretty much let anybody shoot whatever they want if they can hit the target in the first 5 or 6 rds.. dont want any rounds skipping half way and falling into the pits.
And if somebody shows up with a COMP/Brake, then they get moved to the end of the line away from everybody and nobody complains.
Ive shot a bunch of matchs with my suppressed .308, but they did say something about the rules changing thats not goin to allow suppressors in FTR.

Hi, Would the 6x45 BHW barrel with 1:9 twist stabilize the following bullets? Initially they are advertised by the manufacturer and/or documentation as they would stabilize with 1:9
6mm(.243) bullets ============ 1-Hornady 87gr HPBT 2-Hornady 87gr v-Max 3-Sierra 90gr GK FMJ 4-Sierra 100gr GK 5-Nosler 90gr Ballistic Tip. 6-Berber 95gr Hunting VLD - the bullet maker advertises this as 1:9 rate of twist minimum required.
I am not interested in lower grain hunting bullets as they do not have the same design and momentum to handle white tail specially out to 250+ yards.
Thanks.

They shot fine in my 1:9 6X45.nnI haven't tried the Noslers or the Bergers. It won't stabilize a Berger 105 but I am prety sure the 95;s would fly straight. How does that super accurate high speed Lothar Walther barrel that you like so much shoot them? Greg

LH they all stabilize just fine. It is a shorter barrel so shorter can be a tad more accurate but you loose a bit speed. That is why started the research on the 24" barrels. No really for carrying around or anything more for long range. Maybe some F matches so I want to make sure they can shoot some of the better bullets both for hunting occasionally and target. Berger 95gr VLD is advertised as a 1:9 twist by the manufacturer. It should stabilize with the BH 1:9 twist right? bergerbullets.com/Products/All%20Bullets.htmlI have been doing some preliminary testing and I am researching a bit more. I did measure the twist in the new barrel last night and it is in fact a 1 revolution per 9 inches. Any opinions? Thanks.

Try the 95 grain Berger and let us know. You might not have enough speed to stabilize it. It would be a good experiment

In other .243 barrels will stabilize at 2700fps. How much speed do you think is needed in the BH barrel? Also for the 100gr SGK what is the minimum speed needed? Any help during this research is greatly appreciated.
