I have a patternmaster in my 870. No complaints. Shot a couple time with factory and patternmaster at large piece of cardboard. I did see fewer large holes in the patternmaster patterns. I was told not to shoot black clouds out of the paternmaster because the wads could hang up.
buckkicker alot of guys use them in the club and just crush deer with it i got one for my browning bps just havent shot anything yet besides a target but it looks like it will be just as good in that gun of mine too
I use the black cloud choke tube made from pattern master and it works great but if you are looking for long range then you need a tube but I found no real advantage with the short choke tubes. My regular choke tube works just fine. I did notice I will miss more if I am using the long range tube at shorter distance and if you connect at the shorter distance the bird usually is toasted pretty good. I think it personally preferene with the results on waterfowl on how far you are looking to shoot. Steel shot is very expensive as you already know that so, I kinda like shooting as the birds are decoying in.
