10 gauge reload Issues

[Austin J Hawthorne Jr.]

Stan,
Check the crimps of the fired shells that you are loading. If you find any that have even a minor crack, or deformity, where the crimps are those will be the ones that come out like those you've pictured. In case you miss any visually, you should be able to see which ones will be bad as soon as you pre-crimp them. If you want to shoot the deformed shells anyway Craig's suggestion about an overshot card is a good one.

I use REM and Cheddite/RST 10 gauge hulls , I’ve not had anything like that even with hulls that are past their best in reloading efficiency .
