45 ACP weirdness

lol well being new to reloading I might have numbers in front of me and not understand them.: eek:

I am starting to think my calipers are off by 2 or 3 maybe 4 thousands the numbers I come up with seem to be .003 .004 different then other people. I will need to go get another set to test :(

I will confess to buying the cheaper ones :o

Identical problem

I had an identical problem and discovered that on my copper washed bullets I was taper crimping to .473 and some of the rounds did not drop all the way. I then measured some factory .45 and they were all crimped to .469.

I switched to a .470 crimp and have not had an issue since. I have seen 0 pressure signs from the tighter crimp.


HTH,

Since you mentioned different head stamps I assume you collected some brass from different shooter. Chances are you got some brass shot in Glocks. They have very wide 'eat it all' barrels and leave the brass with buldges. Your Kimber Custom II 1911 tho is pretty tight. Hence I suggest getting a push through die and size all brass in 2 steps: push through die and then regular sizer die. I also strongly suggest getting the Dillon stainless steel case cage. You'll be able to see if your bullets are hitting, not so much in your barrel. Don't over crimp and crush the case.
