Speed kills.....but if you can't hit what you are shooting at, then what's the point?!
I have tried several brands but once I found Black Cloud, I haven't bought anything else since. BC in a factory IC choke works for me.
Another issue that I see is all these guys spending 50+ dollars on aftermarket chokes. I have tried a BC choke made by Briley for ducks and couldn't hit a barn with it. While pattern testing my turkey gun, I tried 4 aftermarket chokes tubes. The turkey full that came with the gun outperformed all others.
