and the wagons have circled again -- I was hoping this would not be an never ending tail chase -- no code no violation???

310.120 if the conductors are not so marked.

IMHO, the key would be 310.11 and 300.13 which require certain marking on conductors.
If the conductors in the SER cable are individually identified as ones acceptable by 300.13 the I see no reason you can't strip the jacket and use them. If the individual conductors are not identified as ones acceptable by 300.13 such as NM conductors, then the jacket remains.
Stress IMHO.

I am with Augie on this. Nm inners by themselves are not a chapter 3 wiring method. Ser and mc inners are.

300.12 Mechanical Continuity — Raceways and Cables
Metal or nonmetallic raceways, cable armors, and cable sheaths shall be continuous between cabinets, boxes, fittings, or other enclosures or outlets.
Exception No. 1: Short sections of raceways used to provide support or protection of cable assemblies from physical damage shall not be required to be mechanically continuous.

How did this get past me??? The exception only deals with the short section of raceway as not to be mechanically continuous to protect the continuous cable assembly.

I believe this section may also lend a hand in this discussion

312.5(C) Cables. Where cable is used, each cable shall be secured
to the cabinet, cutout box, or meter socket enclosure.
Exception: Cables with entirely nonmetallic sheaths shall
be permitted to enter the top of a surface-mounted enclosure
through one or more nonflexible raceways not less
than 450 mm (18 in.) and not more than 3.0 m (10 ft) in
length, provided all of the following conditions are met:
(a) Each cable is fastened within 300 mm (12 in.),
measured along the sheath, of the outer end of the raceway
(b) The raceway extends directly above the enclosure
and does not penetrate a structural ceiling.
(c) A fitting is provided on each end of the raceway to
protect the cable(s) from abrasion and the fittings remain
accessible after installation.
(d) The raceway is sealed or plugged at the outer end
using approved means so as to prevent access to the enclosure
through the raceway.
(e) The cable sheath is continuous through the raceway
and extends into the enclosure beyond the fitting not
less than 6 mm (1⁄4 in.).
(f) The raceway is fastened at its outer end and at
other points in accordance with the applicable article.
(g) Where installed as conduit or tubing, the cable fill
does not exceed the amount that would be permitted for
complete conduit or tubing systems by Table 1 of Chapter 9
of this Code and all applicable notes thereto.

For the above section, if a cable wiring method enters an open conduit with a fitting on the end, such as a bushing or a cable clamp, then the cable sheath or armor is only required to be continuous up to that fitting.

Whitebook 2015 Conduit Fittings (DWTT) -- Though we see installations with connectors in female adapters quite often it does not make it compliant & understanding that a cable connector is to be attached with locknut only verifies sheathing box to box was the intent of the code IMO.
1 - "All male threaded fittings and nipples have only been investigated for use with locknuts."
2 - "Fittings with internal female threads (e.g., hubs, conduit bodies, couplings) have only been investigated for use with threaded rigid conduit."
