I agree with the mantra : feeding straight wall cartridges for an action designed for bottlenecks makes the 92 action OAL and bullet shape sensitive, use a RNFP bullet. Pretty sure my issues are ammo related and since I’m not reloading, I need to find an off the shelf solution and I’m having difficulty in understanding what exactly is causes the hang-up in the feed cycle. Based on the photos below of what works and what doesn't, if there are any suggestions on what to look for in ammo that that may have a better chance of working; that would be much appreciated. Suggestions on increasing feeding reliability would be appreciated as well.
A selection of what I have tried:

Going left to to right are:
1) Perfecta 158gr FMJ (1.584” OAL) - works
2) Fiocchi 125gr SJHP (1.587” OAL) – jams
3) Fiocchi 148gr JHP (1.584” OAL) - jams
4) Fiocchi 158gr FMJ (1.575” OAL) - jams
5) Fiocchi 125gr JSP (1.556” OAL) - works
6) Blaser Brass 158gr JHP (1.571” OAL) – works
7) Fiocchi 142gr FMJ (1.573” OAL) - works
-I started off with Perfecta 158 FMJ (#1) and CCI Baser Brass 158 JHP (#6) and found they worked perfectly.
-Figured 158gr flat point was what I wanted, but had mixed results. Fiocchi (#4 above) and S&B (not shown) failed. 158gr FMJ from PPU (not shown) worked.
-Experimented with bullets that had a narrow meplat with mixed results, not a loss since they are a little too pointy for a tubular magazine.
Fiocchi (#2, #3) failed, but the really narrow Truncated Cone 142gr FMJ (#7) worked.
-Found much better results with Jacked Soft Point. Fiocchi (#5 above), Remington 125gr and American Eagle 158gr all worked.
I’m not sure why some cartridges work and some won’t. I would have thought I needed a wide/flat metplat to mimic a RNFP and help push the nose of the bullet over and pull the rear up through the cartridge guides, but the narrowest (142gr FMJ) feeds really well and washes that theory.
I don’t think it’s a crimping issues. All cartridges that jam get the nose in far enough that the crimp is pas the chamber edge. While the Jacked Soft Points seem to have a nicer roll crimp, other rounds that feed have a taper crimp.
What really makes me scratch my head is the 158gr FMJs. Left to right below are a PPU and S&B. Both about the same OAL (1.58”), both taper crimp, similar truncated cone bullet with about the same meplat size … but the S&B jams while PPU feeds fine.
