I have shot 1 1/4 oz loads for a long time through an factory imp.cyl choke tube browning invector plus. The old ones were a slow 1275fps. the load I have shot the last few years is 1425fps At the ranges I shoot (under 35 yards) It works real well but I have not shot at many birds beyond that 35yrd mark for a long time. I won a case of heavysteel last March and I have aquired a couple of paternmaster tubes the same way. This is an 1 1/8 oz load at 1550fps I patterned these through the factory tube and the patternmaster tubes they both performed well the patternmaster decoy choke was a little better in that load. I have not tested it with the heavier load I usually shoot because.... well... if it aint broke don't fix it.
If the birds are close enough I think the most important thing is that your pattern opens up. In close they die easy.
good luck that is my .02 cents.
