Crimp - means of closing the mouth end of a shell case
to secure the shot
Roll crimp - end of
case turned into roll
Pie crimp -means where
shell end is folded over and sealed, looks like cut pie.
Generally the roll-crimp is the older shell
in vintage shotshells and usually they were made before World War II.
Most shotshells today
started about 1960 in the USA and within a few years most ammunition
manufacturers made plastic shotshells not paper. Today there are very few
paper shotshells in production. The same is true of the all
Cartridge vintage shotshell had a plastic seal crimp that is not
like any of the above shells. Click here for photo and
