Easier to take a micrometer or digital and measure to the first constriction.
Then I'd make a dummy round of .360DW brass inserted loosely with the bullet you want to use.
If you see rifling marks on the nose you want to shorten it a touch.
"he.360 DW also has a case length of 1.415 in” (35.94mm) and an overall length of 1.76 in” (44.7mm)."
If you can long load in .357 mag chances are a .360DW will fit.
It is the only thing I shoot through my .357 mag handi rifle now. But I don't have an unloaded .360DW brass to send you.
Interests wide and widely varying.
Happily married 18 years. Retired on SS with lots of time to spend.
Started with .223 Ultra Bull barrel. Added .357 Talo barrel. Added an action and stock set bought here, 7.62x39 barrel. Then bought complete guns .444 Marlin and .300 Blackout. Leaving me at 4 complete rifles plus a barrel. Plus a 9mm stub job bought here, and I have been finding and buying H&R shotguns at our local pawn shop where they seem to go cheap.
