Simple question; I hope. Normally when reloading shotshells with smokeless powder, you simply put the plastic wad over the powder, seat firmly, fill the shot cup in the plastic wad, then crimp it.
I noticed with some clear hulls I was reloading, that some (Not much) of the powder migrated past the gas seal on the bottom of the plastic wad and got in with/near the shot pellets. Again, not much, just something I noticed. These shells has sat for quite a few months since being reloaded.
But noticing it, it made me think that the gas seal may not be as firm as it should. And thus, affect the velocity and such. Now; I've also reloaded quite a bit of BP shotshells where we use over powder cards, some cork/fiber wads, etc. I have a lot of these on hand.
My question is, does it do any harm to add an over powder card over the smokeless powder. The card is very thin. Homemade from cereal boxes. Then, I could put the plastic wad (usually WAA12), fill it with shot and crimp it. I'd think that the over powder card would keep the powder from creeping past the plastic wad into the shot; as well as providing a better gas seal.
Or does anyone think it would negatively affect the pressure too much and be a problems?
Thoughts? Thanks
