Glad to be of help, Mike, and 'Thank You' for providing the pictures to prove it.
A shooting friend and I started playing with this separation of the shot column some years back when looking to improve upon the core-patchiness thrown by the Poly-T device. I have stayed with the 1/8th oz. amount since it pretty much affords a uniform layer of shot to a depth of just one pellet in the 12 and 16 gauges. I suppose a guy could try more volume of shot in the top layer but I didn't know if the jostling effect within those pellets upon (ignition)setback would start to degrade the pattern. Probably something I should have looked at, but I was getting such good results with the 1/8 oz. shot cap that I left it at that.
Mark,
I've been using the solid disc rather than the three-hole as I think the solid platform driving the 1/8 oz. may be a plus for performance. I've patterned the three-hole devices in the past on their own, and feel that they didn't do as well as this separation of the shot column I described earlier. You might prove me wrong on that, but that was my take on things after some time at the plate.
For clays (and especially game), I think it's worth the extra time when loading the Poly-T.
All Best,
Rob
