My usual crow setup is an 870 express with a PatternMaster choke which actually patterns about the same as modified with the cheap 7 1/2"
Here is a picture of my best rally at one stand, in less than 5 minutes I took these crows, 2 on the first volley, 3 on the second wave, and one on the third. I had one get away on the third wave and it was the end of my fun for that stand. Most time I only get one or two before I have move to the next stand.
