I can measure some xtream also if you like.
Great write up. I will be looking into the BB.
Are you running stock glock parts?

Plenty of bullet-makers run 9mm at .355. Like I said, Blue Bullets and Montana Gold both make their 9mm at .355, neither of which are problematic in my guns. (And I've shot easily over 50K Montana Gold out of these guns in the last three years.)

Hornady HAP are .355 OR .356, though the .356 are more likely used in .38 Super rounds in the 125gr version---lots of Open shooters in USPSA use those. (The 115s are .355.)

...but maybe that isn't the issue here after all.
I had assumed that the widest part of the bullet would be the part not squeezed into the case. (I had measured loaded rounds, because I didn't have any loose bullets left.) But...when I measured a couple of _pulled_ bullets, I get .354 for an O.D. So I pulled several more, and they do all measure .355 or .354. That's what I get for assuming.
So maybe O.D. isn't the problem after all.

I appreciate the thought, but I've already had a number of friends take calipers to theirs, and they are all getting .354/.355.
Most of the Glock is stock, and the parts that aren't (a spring here and there, plus the sights) wouldn't make any difference to the bullet keyholing. And I've checked the rounds out of a G17 and a G34, plus the G34 with a KKM barrel...
I've got a couple of people who will try them of out their guns after the next match, just to see if they see anything different. Should be interesting...

I find Zero 121gn or 125gn 38 super JHPs to be about the best in my 9x19s. They run $283.50/3000 at Powder Valley. At Roze Distribution, they run $100.50/1000 for order of 2000 and up for the 121 gn and $109.25/1000 for orders of 200 and up for the 125 gn.
For coated bullets, the most accurate I have found are Precision Bullets (Texas). They are swaged, so they are very consistent in weight and dimensions (right with jacketed bullets in terms of consistency).
Next, if you get any leading in your barrel (not counting Glock polygonal rifling, as I have never used one), then:
if the leading starts at the beginning of the rifling, the bullet is too small or too hard or both (too hard is way common and most 9x19s are much happier with 0.357-0.358" lead bullets, coated or not)
or
if the leading runs along the leading edge of the rifling, then the bullet is too soft or velocity too high (I have never seen this in any of my 9x19s).
Keyholing is generally caused by the bullet being too small in diameter. This can be because the 0.355" bullets you ordered are really 0.354-0.3545" or because they got swaged down what seating due to not expanding the case enough (not talking about the case mouth flare, but actual case expansion) or crimping too much. With plated bullets, you can crimp right through the plating.
Pull some bullets and check their condition and compare diameter to non-seated bullets.

Lots of people really like Zeros. However, since they are about the same price as Montana Gold (or more, for the 125gr Zeros) they aren't anything I'd change to---the Montana Golds work well for me. I'm just trying to find something that works as well, but is cheaper.

Like I said, testing so far has shown that the Blue Bullets are at worst as accurate as the Montana Gold, and in general, seem to be MORE accurate than the Montana Gold, at least in my hands. I'll check them at 35 and 50 yards at a later date, but group sizes thus far have been about 2/3 the size of the MG bullets. Blue Bullets are slightly cheaper than Precision Bullets.

As I said, haven't had any issues with leading at all. Matter of fact, haven't seen any residue whatsoever that is in any way worse than what I'd get with jacketed rounds. But I will bear that in mind. Blue Bullets apparently has quite a number of people shooting their bullets both through Glock barrels, and also in Open guns with extremely high velocities with no leading issues.

As I said, I pulled bullets and there are no plating issues. And the ones I pulled had diameters of .354 and .355. I can't compare to non-seated bullets because I don't have any left. However, friends have put calipers to their Xtremes and have given diameters of .354 and .355.
Regarding "not expanding the case enough"---what do you do to "expand the case"? If that is an issue, what do you do to fix it?
