The highest pattern I saw a 3U lot number shoot out of my two guns was about a 135. That was between all chokes brands I tested. I had a few as low as 80. I actually got two different 3U lot numbers. The ones from Dunns have been the problem child, the midwest ones have been better. Some other fellas were shooting the 3Us and getting 150 to 170 patterns last year.
The 3v lot I've thrown some 180, 170 patterns, but all combined patterns average in the mid 150s. Something's different between the lots numbers.
