Not only noticed it but Kenny and I have had many conversation in person, on the phone and via email on variety of things we have noticed in the pursuit of the paper patch accuracy loads.Wasserburger's contention is that short patches work better on harder bullets. I'm not clear on whether McDowell noticed that part, or not ...
I use 16-1 quite often with the target patched ammo.
The part that seems to slip right past some folks is when shooting the shorter patch and the "hyde" base wrap it takes a few minutes less elevation than does the longer patch particularly at long range distances. It does show up some at midrange/sillouette but not as pronounced as from the long lines.
