I just purchased a MEC sizemaster a few days back. I was wondering from experience what hulls a fella should go with for upland birds and clays.
Winchester AA's and Remington sts or nitro 27 hulls.....Orange WT12 (cheaper version of WAA12 wad) wads for 1 1/8 oz. loads, claybusters didn't like my fingers on my mec grabber (always rough)......Also try the WAA12SL wad for 7/8 and 1 oz. loads...For powder, try green dot for your fast 1 oz loads and clays for your 1 1/8 oz. loads. For fast money loads try the longshot powder.....
