Daryl,

I took your advice and shot some Win AA's and both barrels ejected perfect.I then shot more of the RST's and they ejected poorly again.

I measured the fired hulls when I got back home and the AA's were .007 smaller than the RST's.The AA hulls would go in very easy but the RST's had to be slightly forced into the barrels.

I guess I will use the AA's in my 21 and the RST's in my other vintage doubles.

Thanks for the replys.
