What I wonder about now is what effect, if any, the swell has on performance with plastic shotcups. One of these days I'll do some comparative long range patterning with bare shot and shotcups to check for myself. Actually I had planned to do that in part for a DGJ article and that's why it slipped to the back burner when the editors pulled the plug. I've seen these swells on a few Foxes, Parkers, Winchester M12's, M21's and 101's.

Frank - AH Fox No. 31088 chamber, bore, and choke measurements from Austin's files.
Presuming most folks still reading this thread know 31088 Super Fox was Buckingham's "Bo-Whoop".
