Why don't you find out for yourself. It's pretty easy. Take a Wadcutter case and section it. Then take a regular case and section it.
Just before you haven't heard of it don't mean it doesn't exist.

Look at the picture of the wadcutters fired into jello. Look at the bases. The author used a Remington 148gr HBWC which is swaged from pure lead wire and an Oregon Trail 148gr DEWC with a beveled base which is cast...
You may not have perceived a problem, but ammo manufacturers did and they went as far as retooling to make dedicated Wadcutter brass for these special loads.
I dunno when you last saw a HBWC bullet, but the skirt is not skinny and they run at 8000 PSI. That's not enough pressure to undo the swaging the internal taper of the case did.
The big 3 used to make dedicated Wadcutter brass. It had a different internal taper to allow hollow base Wadcutter bullets to seat flush without swaging down the hollow skirt. Accuracy testing has shown that compressing the skirt during seating hurts accuracy. The pressure in these loads is...
I think you're doing the right thing.
You'd be amazed how case capacity and OAL affects a load when you fire each and every shot through a chronograph.
FC brass is not looser to begin with.
But primers do vary in diameter. WSP seems loose in a FC case. That does not mean the FC case is loose or that it loosens easily.
I find that brass and primers like one another, meaning FC likes FC and Win likes WSP. Mixing and matching often results in...
