Hello, just joined the forum looking some experienced advice. I mistakenly loaded a bunch of 10mm (pistol) and didn't pay close attention to my taper crimp. Consequently, I have a bunch crimped to about .415. I know it should be about .422... These rounds do pass the plunck test in a Glock barrel ( I use a Kimber or Lone wolf while shooting) but very reluctant to shoot these at the range. Also, I have learned that it's best to seat these rounds with the RCBS and then crimp with another die, probably a Lee.
Thanks for your comments
