A guy at my club was telling me how wonderful sabots were and suggested I try a few shots with my T/C 1:48. He gave me ten to try. They shot all over in the 10, 9, and 8 rings. I was so disappointed, I never even tried it again. I can do tens at 25 yds with round balls and at a much lower costs than sabots.
Just my experience, your milage may vary.
