There have been test bullets in the air already. We have found with the original 300 gr 338 bullets that some barrels were tearing them apart. The reason is thought to be the very thin jackets used.
The Broughton barrels have shot these thin jacketed bullets very well from some of the early results we have gotten from Shawn Carlock and his 338 AM.
My two 338 AMs and one 338 Kahn with Lilja barrels would not shoot them, sliced the jackets right along the land centers on every shot.
As such, Richard has been testing some heavier jackets which will range from around just under 30 thou to 40 thou in jacket thickness if wanted. THese are similiar to the heavy jackets Richards original 300 and 350 gr ULDRBBTs were made on and they shot extremely well in all of my rifles with the Lilja barrels.
Not only will the heavier jackets help the bullets survive the launch speeds but they will also help on the terminal end of things as well as the thin jacketed bullets I would suspect would pop like a water balloon on big game. These heavier jackets should prove very stout on big game but the aluminum tips should promote expansion at any range really.
Testing the old designs, that was the problem with the SMK and ULD RBBT at ranges much past 1000 yards, no real expansion unless you get up to the 338 AM performance level.
With the aluminum tips, expansion should be consistant out to the mile range pretty comfortably I would predict.
From talking with Richard, and looking at the bullets I have in shop and have been testing, the 300 gr tipped bullet is longer then the original 350 gr ULD RBBT.
A 270 or 280 gr tipped bullet will be significantly longer then the SMK with a dramatically sharper ogive profile.
BC predictions, well, this will only start another fight so lets just say they should run head to head with the best 50 cal bullets out there but that has yet to be proven.
I have also tested some 30 cal versions and those are being worked on as well. The ones I have are 215 and 220 gr and make the 240 gr SMK look silly.
All in all, once the minor bugs are worked out, these bullets will offer a ballistic advantage over conventional bullets that will have to be seen to believe.
Only with the long solid VLD design bullets would you be able to rivel the BC of these pills and then they will not compare with the new aluminum tipped Wildcat Bullets as far as barrel to barrel consistancy performance.
This is cutting edge stuff Richard is doing. Truely amazing and will take us to new levels. Just running some preliminary numbers it looks like 3000 yards may be realistic with super sonic velocity out of rounds like my 338 AM. That is something no one has been able to achieve yet with conventional bullets, let alone a lead core bullet.
Richard is setting up to offer these in all calibers from 25 up to 50 cal I believe.
These will also be used in my soon to come 375 AM and 458 AM.
They will not be cheap but they will be significantly cheaper then the LRB bullets which will be the only real ballistic compeition for these bullets and then accuracy will not even be remotely as consistant as the Wildcats.
More to come very soon. I will be testing some of the heavy jacketed 338s tomorrow if the weather holds out. Will post my results.
