I had a customer come to my shooting ground to pattern a new gun he had. The gun had 3” chambers and from memory it was a backbored Browning. He was using 2 ½” cartridges with fibre wad. After a few shots he came over very apologetically as he had put 3 big dents in the plate. In one of the dents was the remains of a balled lump of shot.
They tried the cartridges through a Berretta they had which produced excellent patterns.
I have tried patterning various Brownings with shorter chambers with no problem and this client reported no problem with plastic wads.
It was only a few shots so was not definitive – just a bit worrying with the wrong combination.
