Thread: A400 choke changing poi

I have a a400 extreme Unico and using a patternmaster black duck choke it shoots a 70/30 pattern at 35m. I'm now using a factory modified which has brought it back to 50/50. I'm curious to see whether anyone else had similar experience. I originally wondered if it has been made that way to accommodate for abit of drop for when range is getting abit further away. Before pattern testing and changing to the modified I was constantly shooting over the top of close birds but smoking them when they were 40m out.
