Brass Puzzle

[tommygun13]

Recently reloaded 25 - 2x fired Hornady brass 6.5 creedmoors, Horney 130 gr eld match all within salami specs using Redding NM-C dies. 22 fit like an artificial inseminator’s glove. 3 would not chamber. Remeasured and all three exactly as the other 22. Thought it may be a shoulder bump thing, so resized them in the FL die. They still refused to chamber. It is now me against the 3 of them, and has become very personal. Any suggestions, other than throwing them out.

You remeasured wrong. If three don’t fit but 22 do, then there is a dimensional difference somewhere. Measure at the base (at the expansion ring), shoulder, neck, ogjive, case length, etc.

Start to finish process could help identifying issues. What types of measuring tools etc.

mmmm...salami specs.

FWIW, Hornady isn't known for making consistent brass. It's normally ok, but common to have one or two pieces close or out of spec, from my experience.

Just spitballing a hack but you could darken the offenders with a marker and try to chamber, the area of resistance might/should shine through. Of course measuring everything as mentioned above should find the problem.

Was the brass fired in a different rifle?
Color them with a sharpie an see where they are making contact.

Also is that Genoa salami?

I recently went through the same thing with 40 rds loaded for a 6.5 prc virgin adg brass and one would not chamber, got home and dismantled the loaded round. I thought I had an odd piece of brass but, it ended up being the bullet, just reloaded it with a different bullet from the same box and it chambered perfect. That bullet measured .267 plus the brass made it tight to fit. Hope this helps.

thanks for the input. same rifle, tools are hornady comparator, sinclair case guage, redding fl and seating dies, have remeasured and remeasured ogive, coal, case length, as to diameter and length sinclair gauge says fine, fl resized. reloaded with out powder, fit magazine perfectly, and after all that. The same 3 still won't chamber. Only thing it could be is headspace, but fl sizing should have taken care of that.

anyway, did the marker trick Buckley suggested and all three of the little bastards show wear in the same place. It is on one side at the top of the neck. so that must be where the jam is, but how does that happen. is it possible the necks were thicker on one side. it seems to me that even if they were, the sizing die should have taken care of that. shot probably 100 rounds of the same lot brass and only these 3 have given me the problem.

If you measured the neck diameter of those three cases and it is the same as the rest, then that’s not where the jam is.

The neck scratches are probably just from chambering where the ejector is pushing it against one side.
