kgonzo,The problem of poor pattern could have more to do with the ammo(shot charge weight)than with choke.You could do some expirementing.Briley makes an excellent tube.A problem with 12 ga versus 10 ga is even thought the shot charge weight is the same(2 1/4 oz) the 10 ga performs better because of the larger bore.The 12 ga has a longer shot string and doesn't pattern as well.This patterning problem is sometimes made worse by larger shot sizes.In some cases the heavy shot charge combined with large shot size and fired through a tight choke results in a blown shot pattern.In other words the blown shot pattern has holes in the pattern etc.I would try some different loads (2 oz ??)and using different chokes.You might find the 2 1/4 oz load works better with a full or modified tube in it,or maybe winchester ammo performs better than remington.You might also find the 2 oz load works better than the 2 1/4 in your gun.<BR>~~~~~~tom
