A little background. I've been reloading metallic cartridges for decades but a couple years ago now I got into shotshell reloading. I do 12, 20, 16 and .410..should do 28..but don't have any gear for it yet. I cast my own slugs, 00, 0 and #4 buck, and drip #6 and #7.5 shot.
I made up a bunch last year..loaded a few cases of each that I had been using..and now I'm finally low again.. During this time..ive made plenty of trips to the range and picked up possibly thousands of hulls. I keep rem sts top gun and aa hulls sorted. And the rest I just sort into 3 groups.. Taper or not, and if any have cardboard base wad. ( and of course sub sorting by size... ).
I probably have 1000 generic hulls that I can fire and forget. Some ranges let you pick up..some don't.. I use those unsorted ones at the no pickup range.
In any case.. I have plenty of hulls that just don't crimp well. I'm using Lee load-all II's and hand tools for the .410.
Some federal in 20g make ugly as sin fold crimps..no matter which starter you use..and there are other hulls I plan on cutting down as well..in 12 and 20. I do roll crimp some..but the roll crimp tool doesn't play nice with plastic overshot discs..and I tend to prefer those to overshot cards. Also for some of the slugs I use, at least one has a profile that the roll crimp rotary tool won't work with..cant roll the edge close enough to the slug to keep it from having some play...nose is longer on that slug..and the rotary tool doesn't have any relief for it..etc.
Been reading up on elmers glue and hot glue for holding slugs in or holding overshot cards in. Tried elmers..didnt like it. Have heard very little negatives on the hot glue.
Wanted yall's opinion. Any trouble using hot glue to retain slugs or overshot cards..or plugging holes in imperfect fold crimps that let the really fine shot out sometimes?
