For your info from my experience this year. I have used the neon green wads from downrange for the past few years ( on a MEC ) great wads. I am using them now on my spolar, but they only work on remington hulls. If you are using winchester hulls you need to use the downrange pink wads that have the same bottom as the spolar gold wads. I am finishing up my neon greens and bought a case of the pinks they run a few dollars more but pattern the same in my gun. The greens do not fit in the AA hulls they pop up and spill shot because of an air pocket that forms in the AA hull. I worked with Dixie on this from spolar and Kevin from downrange on this. Just trying to save you a headache.
