Jacketed bullets in .401" are for .40S&W and 10mm, like other semiautos, 9/.45 etc, they use the type of crimp that does not have a crimping groove or cannelure

.38-40, like other revolvers including .38/.357/.44/.41 etc uses the other type of crimp that requires a crimping groove or cannelure.

I can't remember which is taper crimp and which is roll crimp

I remember seeing a tool to add a cannelure to jacketed bullets, and I remember seeing Buffalo Arms offering jacketed bullets with the cannelure added.

one can load without crimping but then there is a risk of other bullets moving under recoil

you also have to be careful with lever actions to make sure the tip of the bullet or edge of its hollow point won't risk putting pressure on the primer of the round in front of it when laying at the angle it will in the tube due to cartridge shape.

shoot good!
