To avoid hijacking another thread I am starting a new one.
I have been reloading a fair bit of pistol ammo with range pickup brass. I’m noticing a bit of an issue with case mouth flaring not being consistent.
Within one batch of head stamp sorted .45acp or 9mm the flare on the case mouth may be so narrow as to barely be able to stand a bullet on it or so wide that it has a hard time starting in the taper crimp die.
I am suspecting variance in case length being the culprit by changing how deep the case goes in the flaring die by a few millimeters.
I measured a random batch of .45acp Winchester cases and case lengths danger from .85” to .96”
I was surprised to see a range of .11” difference.
Before this I had just done a quick go/nogo check for case length.
I think I’ll try trimming this batch to the shortest case at .85 and see if the flare is more uniform.
The case trim length is .893. Do you think I’ll be creating any problems?
Any advice and education is encouraged and appreciated.
Here is a picture of columns of case lengths.
