I found some images of special interest.
"Bobbed Bullets, Ltd." (not Bubba, not Bobbuh, just Bobbed) is henceforth the name
of the up and coming bullet maker with no proprietary secrets.

Sir Bob bobbed a 450-gr A-Frame to make a 402-gr X-A-Frame FNSN that worked through his Marlin 1895.

Below is his interesting lineup with a bullet I cannot identify, the brass or bronze-jacketed RN FMJ,
that looks like a heavier version of the Thompson Center Bone Crusher 400-grainer:

Who is the maker of the Bone Crusher type of FMJ round noses ?
Bob did not identify it in his blog notes.
The top bullet of the three above is said to be a 600-gr Barnes,
with a cannelure and an ogive I have never seen on the 600-gr/.458-cal Barnes Originals.
Maybe Sir Bob will enlighten me, or sumbuddy who know ?


Sir Ron,
That 600gr was indeed from an original plastic box with Barnes name on it, which I no longer have. I think (if my memory hasn't completely failed) that it went with the CZ550 when sold, thinking I couldn't use them in my Ruger #1, .45-70 LT. Too long for stability in the 1:20 twist rate. In fact, I did try them at about 1900 fps from that rifle and they showed tilting in a target at 100 yds. But that wasn't all it could do in that rifle; I believe 2000 fps was safely possible.

The 500gr FMJ RN was offered by Hornady at one time until complaints came in over it's performance on big DG. I've only fired a few, but haven't tested them in media. One day I hope to. They are called "ENCAPSULATED" ON THE BOX OF 50, of which I still have most. The thick bronze jacket of about .075" "encapsulates" a hardened lead core with a copper "cap" on the bottom end. I must try them in tough media when all is in place. I've no doubt they would "sail through" the same media in which I previously tested several .458" solids and softs.

Many thanks for your continued excellent work. And get that knee back to health soon!
