Sihouette is good cross training. And smallbore matches are fairly common. (vs highpower finding 500 yards)
The targets are somewhat different in sizes etc.. shape too. Turkey is the least forgiving to me and most like a highpower target.
BUT remember David Tubb, was also a Silhouette king too... El Rey was the name....so it must work.
OT here, but pistol matches bullseye rapid fire strings were REALLY great cross training for highpower rapid fire trigger control....
