Dunno who else might be loading these so thought I'd throw this out here. Using data from Hodgdon and others for a guideline.
Got in a batch of RMR 124gr MPR Nukes to fiddle with. The Nuke is .544" long and the XTP is .573".
Had ta seat'em at 1.080 COAL to get a good plunk-n-spin in the CZ. Tested fine in several others as well.
Tried'em with some Win 231 @ 4.1 and 4.3gr in a 4.32" barrel.
The 4.1gr was @1060fps and 4.3gr was ~1100fps. All cases and primers looked GTG and velocity seems somewhat in line with data from Hodgdon for a switch.
I'm a tenth over listed max but seated out .025" more with a shorter bullet in a slightly longer barrel.
Spread was minimal. Good case fill. I don't think you could double charge and still seat a bullet.
Tried it in the P365XL. Got the same velocity and accuracy was very good.
Got a buncha plastic gallon water jugs to try them out in next week..
They've got a pretty big maw on'em. Oughtta be interesting. The last pic is of an Everglades 124gr JHP RN Version 2 for profile comparison.
