Thanks for the input. These have the silver base, and say Top Gun on the side of each case, and also on the empty boxes. I am familiar with the paper base as I have reloaded 16ga Federal hunting loads but these are plastic base wads like the Range and Field. There was a 40 gallon barrel full of once fired so I filled half a trash bag to try, also lots of 3inch Premeum turkey load cases,just want the right data.
Savage Arms uses our range for testing and when the Turkish companies bring over new shotguns they blast away as fast as they can shoot until they can't hold the gun even with gloves. I've seen it, the Turks are real proud of their product.
I've loaded rifle/pistol for over 40 years but pretty new to shot shell and all the warnings about components makes me careful so any input would be great.
