At the moment I'm loading RST's using SP-10's for a friend , it's my intention after getting his hundred taken care of I wanna try four or five of the BPI wads in both the REM and RST hulls . My standard charge of 30 grains of SR725 shouldn't be an issue in either hull with 1 1/4 ounces of shot and a couple red beans to take up space . I had the powder migration deal with 8 gauge WIN hulls using the SP-8 wad but that was more of a matter of displaced air pushing the powder as they were being loaded . They however break targets alright and once those hulls have been fired once you can't see the powder migration so easily .
These BPI wads are more of a I wanna try them type thing . I'd wanted a few bags when they were still made by Gualandi and had them on back order at a couple places for over a year . I've got more than enough SP-10's to least me the rest of my existance I think , seems to me I now have between 6 to 7 1/2 thousand SP-10's .
