Barrell adaptors
 

The 2007 Browning catalog list shot shell reducers sold in pairs. Do they work in any doubles or just their own? I have an Italian O/U 12 guage. About 5 boxes of 16 guage shells. I also wonder how the pattern holds as it seems like the wad would open up in the bigger barells. I know it is only for a fleeting second!

:) Thanks, Bob
