38 Super has a nominal bullet diameter of .358. I'm thinking the .356 bullet you mentioned is just an alternate size for 9mm in the heavy bullet.

It's for gas sealing. Typically jacketed bullets are .355 while lead and plated bullets are .356 because they are softer and will form to the rifling. At least that's what I've been told. I've shot both Berry and RMR .356 and Xtreme .355 plated bullets. I notice absolutely no difference in accuracy or operation. I was skeptical when I first started using Xtreme, but no more. It's all I buy at the present time (they are the cheapest of the plated bullets available) if they raise their prices or one of the others lower theirs, then I'll switch. I shoot a lot of rounds per week (~1K) so price per bullet is important (as long as the accuracy doesn't suffer 
)

9mm and .38 Super are both .356/.355 bores... Generally lead will run .356, jacketed .355
I would bet those jacketed bullets listed at .356 are actually .355.
IF they are .356, with proper load development it won't matter

They do offer a double dipped heavy plated with a concave base to tell the difference from the light plated bullets in their 9mm line.
Might explain the larger dia................for the bullets made to be pushed faster?
the 147 comes in .356 and .357 dia.

The .356 are listed under the "heavy plate" but your answer would be best obtained by calling or e mailing them.
Xtreme bullets: sizing
I noticed a similar situation with their 45 caliber bullets.
Their 255gr bullet, typically for 45 Colt, is listed as .451" & their 225gr bullet is listed as .452". I called & they said the 225gr should be listed as .451" (it's still wrong on the webpage).
I just received my recent order and the 255gr truncated FP bullets, with a cannelure, average .4516" & the 225gr truncated FPs, no cannelure, average .4518". These are their standard plated, Superior Plated Bullet (SPB), bullets, rated to 1200fps.
The 45 ACP 200gr SWC bullets averaged .4516" (listed .451"), also a SPB. The 45 ACP 230gr RN-HP bullets run .4526" (listed .452") & are their Heavy Plate Concave Base (HPCB) design rated at 1500fps.
They also have some SPB 200 & 230gr RN bullets that are listed as .452" but I haven't bought any of those & can't confirm their sizing.
The SPB 240gr RNFP 44 caliber bullets I got average .4294" (listed .429").
As in the past, they shipped out ($5 flat fee, UPS) promptly the next day, packaged them well, & their quality looks excellent.
Now to load them up & get to the range.

I have some of Extreme's recently received 45 ACP bullets, 230 grain RN and 185 grain TCFP. The 230 grain standard plate RN bullets measure in at 0.4523 inch and the TCFP bullets measure in at 0.4519 inch.
I've been loading with Extreme's plated bullets in 38 special, 40 S&W, and 45 ACP for about 3 1/2 years and have found them to be quite "range worthy" and accurate.
Fact is if I'm shooting my handguns poorly the fault lies with me, not my bullets, sights, or firearms. A lesson recently reinforced because I've been spending a LOT of time shooting and learning with a new AR15 I built myself for my 60th birthday. Just two months of shooting a handgun for a magazine or two after shooting the AR has resulted in a strong case of the "low and left" syndrome that will likely require a month or more of steady practice.
