A true "Gun Guy" (or gal) should have familiarity and a modicum of proficiency with most all firearms platforms.
The idea is that it allows the full length sizing die to do its thing all the way down to the extractor bevel. The extractor bevel on the Super and Super Comp brass is enough closer to the case rim that the die won't reach the last tiny bit of case just ahead of the bevel. To get that last bit of brass sized would require the use of a roll sizer which isn't a cheap piece of machinery.

The rationale for this; in the day, in order to make Major with .38 Super we ran some exceptionally HOT ammo (handloads). It was not uncommon for folks still shooting unsupported (non-ramped) barrels to have case heads swell, with this high pressure ammo, to a point it was not possible to size cases well enough that they would chamber reliably after reloading.
Probably NOT a concern today as the "Major PF" was reduced, and I haven't seen a non-ramped Super barrel in a Gamer's gun in in a couple decades.

Okay, I see the benefit of the TJ now, thanks, guys!
Is there any downside to the TJ bevel?
Also thanks. I didn't know that.
I did some searching.
I didn't find any downsides to using .38 TJ instead of .38 SC.
I have a Colt in .38 Super and a Ed Brown 9mm semi drop in barrel. Both work reliably with the super being the one I trust the most but only because it is the original caliber. No change in extractor or ejector for me. With the 9mm barrel in it does not eject as far as it does with super but, the cases do get out. I use the 9mm barrel for local matches like IDPA where power and distance won't be an issue and super when shooting 2 gun where spinners and longer ranges are the order of the day. I zeroed the sights with .38 Super Auto, 130 gr. bullets at 36 yards, the same zero I use for my carbine.
As for magazines: I use dedicated 9mm mags with the 9mm barrel. I tried using my super mags with the 9mm with mixed results. I use Tripp and Wilson super mags and a mix of Tripp, Wilson, Mecgar and Springfield [9 round] for the 9mm. All have been reliable.
