Greetings,
Been thinking about a new 243 LBC build, but I'm not certain yet if it's going to be a general purpose hunter or a benchrest rig. (However, I'm leaning towards a 20" thin profile hunter.) I'm trying to weigh the pro's and con's of various barrel profiles. So, my question is, how much performance is really sacrificed between a thicker/stiffer barrel like a bull or NM barrel and a thinner/lighter barrel? Are we talking sub-MOA differences or is it generally more substantial? I understand that the barrel harmonics tend to favor the bull barrel, but does anyone have any hard data on what the actual differences would be?

I understand that the barrel harmonics tend to favor the bull barrel, but does anyone have any hard data on what the actual differences would be? There is no difference in accuracy between the lighter barrels verses the bull profile. Where the bull profile shines is during sustained fire. As we all know, when a barrel is fired it heats up. The bull will take longer to heat simply because of the mass. The light barrels heat faster but are just as accurate as the bull. They just can't sustain group after group. Performance wise, the only change you will notice is in barrel length. The 243 LBC likes long barrels. The 20 inch barrel will work great for a hunting rig, but if I were building a rifle for a target gun, I would go with a 24" barrel. |

I can't really say "what the difference" might be, but I have an 18" "slim" profile which gives me honest, repeatable, MOA for 5 shots with 7 shots tending to run out to 1.25 - 1.5 MOA using a 4X scope and 70+ year old eyes. It weighs in at 7# with optics but no magazine. I've carried enough "stuff" in my life - lighter is better, at least for me!

Thanks for the replies, that information definitely helps. BTW, do you know if the 243 LBC barrels ship with the Type I headspaced bolt, or if the bolt needs to be ordered separately?

The 243 LBC does not typically come with a bolt. I am sure, with a phone call, you could order it that way. BTW Look at the standard profile for an all around barrel. I'm sure I can speak with authority on this, I've probably shot more rounds from a 243 LBC than all of the board users combined. |

I'll second what Ritch said. I've probably shot second most rounds through the 243 LBC. Just a heads up on brass. But the Lapua and be done with it. Best quality and the stuff last a long time compared to the Hornady It is also far more consistent and price is maybe $0.05 difference.

That's what I'm running on my other BHW barrels: 308 (Rainier Select), 7mm-08, and 264 LBC. I'm still on the fence on this one, but leaning towards lighter weight. |

That Lapua brass looks nice, but is it really worth the cost of admission? $80-100 per 100 seems a bit steep to me, but then I'm fairly new to the wildcatting world. Seems like it would be more practical to buy loaded 6.5 Gren and reload it after "once fired". Or are there other considerations for resizing to 243 LBC that favor the Lapua brass? |

With the difference only $8.00 per 100 it's a no brainer. If you don't try to push the brass hard Lapua brass will out last the competition as much as two to one. The other brands are known to be inconsistent in weight and have softer case heads. |
