Went to the range with my dad today to put some sabots through the new rifled barrel and scope combo that he put on his 12G Mossberg 500. The remmington solid copper sabots did not group well at all. Typical grouping was 4"-6" at 50 yards. The winchester XP3's were a totally different animal. They shot sub 2" groups. We wanted to try the Hornady SST's but the gunshop only had the Winchester XP3's which looked like a comparable slug. If you try the Hornady SST's let me know how they do.

Thanks,
