Okay here goes I just started loading 10mm using large rifle primers due to necessity. And I really don't want to hear that they're .004 longer than large pistol primers, isn't the 10mm a cut-down rifle cartridge. They fit perfectly in my setup they work perfectly after 150 test rounds.
I have also watched a number of reloading companies videos where they have pressure-tested different cartridges using both large pistol and large rifle and small pistol and small rifle there was no noticeable difference in pressures.
I did run the cronograph and there wasn't one bit of difference in bullet speed so that would tend to make me believe that the pressures would be very close everything else staying the same. Why do some people post saying I wouldn't do that they're longer they have done no research or testing on their own
