My System One did not appear to like conicals either since I tried maxie balls,ballets and several no excueses I needed a load for elk that was legal so I tried a few things what I ended up with was 85 gr RS and a over the powder wad with 20gr cornmeal and that shot all of them under 4 inches and would put the ballets and maxie balls into 2.5 which was good enough for what I needed.
