I had an opposite experience and found the baffle more consistent. When I bought it some years ago I tested the powder drop weights (with/without) while using IMR "PB" powder and a particular bushing I was routinely using at the time. The extreme range of variability (3rd sigma as in statistics) was > half less with the baffle, than without. That's with 20 powder drops in each mode and the data is in my reloading log book. I still have a lot of "PB" squirreled away and like it for composite barrels but have gone to 700-X for paper shells and to E3 in plastics for my casual 12-gauge clays shooting with steel barreled guns. Just the way I do it …….
No, I didn't do the with/without drop weight testing using the baffle with either of the latter two powders.
