Kicking around the idea of a 12.5". Any ideas on velocity? Would it be worth it, or is a longer barrel necessary.
Currently have a 12.5" 264lbc, and love that. Any thoughts on how the two would compare?

Any thoughts on how the two would compare? Is it worth it? You have to decide. Depending on what you want to do determines that. Compare in what way? The 264 will be faster for same same bullet weight but the 243LBC will shoot lighter pills. Not my cup of tea but it would have a cool factor. Greg |

Guess what I'm wondering about is approx velocity. How is an 80gr 6mm gonna compare to a 110gr 6.5mm at 200 yds. I have zero frame of reference on this. I like the idea of something different, just don't know how practical it is...

Just out of curiosity, what is your intended purpose for the rifle? I get the itch to do weird things on occasion too just for the hell of it but practicality usually wins out.

COMPUTER MODELED NOT REAL WORLD TESTED!!
243 LBC 87 GRAIN HORNADY HPBTM 24" 2976 12 1/2" 2499
264 LBC 120 NOSLER BALLISTIC TIP 24" 2598 12 1/2" 2246
The 6.5 looses less per inch. Pretty much what we have experienced in these two cases.

Someone on a forum ( no link sorry ) showed about 300fps less on a Savage Striker 243 Win compared to a rifle. What Greg shows is comparable.

Going to burn half the powder outside the barrel.

Yeah, for hunting. Deer and pigs. Would probably be the first of a pair or ar's....second being a more traditional length barrel. The 12.5" length is very handy for a truck gun with can attached, for dispatching swine. I'll probably do it just to have something new to keep up with....

I know I'm new and late to the post but from a mumbers standpoint I'm shooting a 12" 6.8 spc with a BHW barrel and a silencer. The 90 grain bullets chrono at 2500fps with the factory ssa/nosler 90bsb.
I was reading posts to see what the pros and cons of long-short barrels.. just my 2cents if anyone is digging for info.. It seems the 6mm lbc shines with a long pipe..

It seems the 6mm lbc shines with a long pipe.. Both the 6.8 and 243 LBC will do well with long barrels. Don't buy into that garbage about the 6.8 or a 6.5 Grendel rounds being optimized for short barrels The 6.8 guys insist theirs is superior because of that. Horse hockey. You load them and shoot them long they both do well. You load them and shoot them short they both do well. You stick a quality MODERN bolt in an LBC and it will stomp a 6.8 like a five year old in a water puddle no matter what the barrel length. I shoot more six millimeter chambers in 500 yard F-class matches with an AR than anyone in the US. When you put it in an LBC you have made one of the best balanced rounds you'll ever have. I've shot 6X45, 6X6.8 and the LBC in matches. Guess which one will be taken to 1000 in matches this winter. Greg PS Welcome to the board. Enjoy. |

LOL Greg.
Finally bought my 24" bull 243LBC today from BHW - love my other 4 BHW's - can't wait to shoot this one - saved the best for last IMO. I like the 277 Wolverine in a 12.5" barrel - gets all the powder burnt like the 300 blk does in my 10.5" - performance comes close to 6.8 SPC in same length barrel (different powder - like shooters world black)

I'm sure it will do all you want easily. Keep us posted as it develops. As to the Wolverine I don't see any reason for it. The 6.8 is about the floor for me in something of that diameter and I don't see any reason to load down to less than that. It has nothing to offer in suppression as bullet weight is king in that area and last I looked a 220 .308 out does anything in the 6.8 bore. It is ballistically impossible to give up that amount of capacity and hope to run "close" to the bigger case when loaded to sane pressures. I've run the pressure numbers and the WLV is on the ragged edge in many loadings I've seen. Kind of like a Fireball will never equal a 223 in my opinion. The cheap brass argument is pretty weak for me and with Starline coming out with what appears to be pretty good quality 6.8 brass at a low price that one goes away quick. A penny or two difference would not push me to the smaller case. I want to have flexibility and the base 6.8gives me more of that. For a similar historical perspective the 6.5 PCC was a precursor to the 277 WLV. We found early on that the idiots running it were so far over the top it was clearly unsafe at advertised and much published data. An upper and ammunition was furnished and when the first "safe"loads registered 65,000 on the pressure trace eyebrows were raised. When the gauge went away asbin the strain gauge wss blown off the barrel yhegear got packed up and that was that. It too claimed that it could "almost" equal the Grendel. I have one of them and it is less than impressive I'd take a 6X45 over it all day long and be happy in my work. Lots of design flaws that are obvious if you just pick one up and look at it. At the end of the day as long as we are all having fun it makes no difference how we get there as long as we do it safely. Safety is a matter of personal opinion and judgement. Be safe and have fun. Once again enjoy the new tube. Greg |
