I hope this is not too silly of a question... I recently got my hands on some shotshell reloading components and tools. Just for grins I was playing with a paper hull. It had the mouth pretty ragged from a loading or two. The short of it is I loaded the shell with powder, an overpowder card, 3/8 felt wad, 7/8 oz of #8 shot and an overshot card. I cut the ragged end off the hull and roll crimped the case. It looks great. But it's only 2.1" tall. I'm loading light for an antique 12 ga with a 2-3/4 chamber. I'm assuming these will shoot safely being short. Thanks.
