I agree. I had a a 12 to 28 set of Seminole Chambermates and they worked well enough provided I used premium ammo (Winchester AA, Remington STS or Federal Gold Medal Taget). Other brands such as Kent or Challenger wouldn't eject properly. I would also get a hollow sounding report occasionally which I assume meant the wad didn't seal properly.beretta boy said:The Briley Chamber inserts are " O.K. " for occassional recreational use.
If you are going to shoot the small gauges in any quantity or competitively, tubes are the way to go.
