Shotgunjones, I appreciate all the information.

You have confirmed that my AA’s measure the same as yours,.882”. At .880, they fit into the gun no problem.

Also, thank you for the Remington STS measurement. It gives me another hull to look for. The Cheddite/RST measures .875”, so that’s on my list as well.

I have decided to not open up the rim cut and just try and scrounge up some STS’s or Cheddite’s.

I really appreciate everyone who has contributed to the thread. Thanks to you all!
