Forgive me if this has been covered, but I searched this forum and didn't find an answer...
I've been reloading .45 ACP and seating/taper crimping at the same time with an RCBS die (I'm going to buy a Lee FCD soon). I measure case length using a Dillon OAL guage after resizing and after seating/crimping. I drop tested some of the finished product in my 45 barrel and the rounds fell nicely in the chamber, but needed a gentle push to seat all the way.
So, my question is how do you know you have the proper amount of crimp? I read in Wilson's 45 guide that he uses a taper crimp of .469 at the case mouth. Is it just a matter of crimping and measuring across the case mouth with a caliper?
My son made an obeservation while we were shooting Sunday and said that my 45 was throwing a lot of debris out the barrel when I shot reloads. Is this unburned powder that didn't ignite due to too little crimp? i.e. bullet starts to move before all the powder?
Thanks!
