Re: High BC 375 Bullets
I am not supporting the LRBT bullets in any way but instead the barrels that shoot them. I have had several conversations with Barney Lawton who is making the barreled receivers for Chey Tac and from what I understand from him, the "Chey Tac" barrels are not dramatically different then a conventional barrel.
The bores may be slightly different diameter but if you look at the range of bore diameters from different barrel makers, its us a drastic variation. Thing is with a cup jacketed bullet, most bore diameters will shoot very well if the other aspects of the barrel are correct.
From what I understand from Barney Lawton, the "special" chey tac barrels do not have an unusual bore diameter, just a specific bore diameter designed for these bullets specifically.
The other difference is that they have 8 lands and grooves instead of a more conventional 6 groove design.
Also, the grooves are shallower then a conventional rifling design. Again, this is because they are designed for the solid bullets and this reduces engraving pressure dramatically with these solid bullets.
In testing my 7mm AM with several different barrels with a wide range of rifling designs, I believe that the Lawton "Chey Tac" barrel design would be very successful using heavy for caliber, thin jacketed bullets driven to high velocity. Sadly, the smallest caliber offered is either 30 or 338, can not remember off the top of my head.
The benefits of this barrel design should also work just as well on thin jacketed bullets such as the 200 gr ULD RBBT which is based on the J-4 jacket.
So I would not say that you would be stuck using only one bullet. These barrels should work very well with all conventional bullets. Its not a problem of the barrel being so dramatically differnet that you can not use any other conventional bullets. The problem is the LRBT bullets themselves.
I will be ordering in one of Barneys 338 barrels here in the next couple months to test with my 300 AM and prove this theory of mine that the Chey Tac barrels have more uses then just shooting LRBT bullets. We will see how things play out, hope it works [img]/ubbthreads/images/graemlins/grin.gif[/img]!!!
Just wanted to point out though that from what I understand, these are not "only one bullet barrels".
These bullets ARE a "one barrel bullet" though!!
