One question regarding the plastic cases. I have read on numerous occasions that Black Powder burned too hot for use in plastic, that cases would be very short-lived. I have thus refrained from loading BP in plastic, so have no personal experience.

I have a W&C Scott 12 ga pinfire I have been wanting to make up some shells for, but for the work involved would want more than a couple of shots per each.

Where are you saying the Magtech brass is too thin? Is it for the purpose of swaging the rim or for holding the "Valve"? I could turn the rim so that would not be a problem. If there is not enough Meat to provide strength enough to hold the cap adapter that would another matter.
I have a box of 25 of the older Magtech 12 gauge brass which used the Berdan primers which would be a good use for them if I could work out a suitable conversion for them.

I have looked into an original pinfire hull that I have. It seems to have a 1/8" wad with a hole in the middle to hold the cap. See photo. I'm going to try and duplicate that as one of the methods I'll try.

Not a bad idea Mike

The pins can dent the thin Magtech case walls at impact.

The Magtech case is a very thin walled 'baloon head' type of construction.
Also it doesn't use a 209 primer.
A fellow could simply drill the base of the primer pocket and tap some suitable threads in the primer pocket walls and thread in a plug, then cross drill the firing pin hole.

As noted above, the case walls are thin and if the percussion cap is nested against the inside case wall opposite the externally protruding firing pin the case can dent from firing pin strikes.

would Paper Federals be a good alternative to plastic? Old ones have brass rims while the current ones have steel rims.

Most likely as the originals were paper.
