Had some Clays loaded in 40 cal. (blue bullets 200gr, oal 1.208) and some Claydot also loaded to the same load and FPS. Maybe it was my imagination but the Claydot seemed to have slightly LESS felt recoil. Yes, I have heard all about the pressure spikes of Clays and temp sensitivity, cleanliness etc, but this was a room temp for both, tried several times, result was the same, Claydot felt slightly softer. Interested in hearing about your tests...
