bit more popular if there had been more bullets with a cannelure for reloaders. I used hard cast lead with a gas check and a cannelure that were intended for the 38-40 for most of my 401 GNR and 400 GNR load testing. I tend to use the fine 180 grain gas checked .401 caliber bullets made by Montana Bullet Works for my hunting loads as they have a cannelure.
Reloading for both cartridges can be done with non-cannelured bullets but a good taper crimp needs to be done for better ignition and better velocities.
