Ericson, I have been shooting them, and have a whole bunch on order. Here is my take.
The bullet is fat, the ones I have are at least .2436 at the shank to boat tail junction. Yes, it does have what can be described as a gas ring at that point. Just forward of this, and for at least 5/32 up the shank, they measure around .2432, before a very gradual taper into the ogive. I don't know what the actual o-give number is, but they set up pretty far into the case, so much that I went back to a .045 free bore. I think a .060, or perhaps longer, might even work, but I do not have a reamer at this time with that free bore.
I told Bart that this thing looks like a old Fowler Bullet with a boat tail stuck on.
For what it is worth, when I switch from Barts .790 boat tail to this bullet, the set up is identicle. Which brings me to this. They love to be jumped. And I mean really jumped. I set the bullet up to where I can see the faintest of marks, then I move the bullet .015 further into the case. This is the way quite a few competitors are shooting them, I have never jumped a bullet this much before, I don't know why these, (and the .790), perform best when this far off the lands. But I don't argue with the targets..........jackie

Bart makes two B/Ts a .790 (65gr Bart Tail) and a .825.
Hope this helps.
