my dad does mounted shooting and he uses balls of sheepskin strung on a leather thong to go in the horses ears. not sure if it helps or not.he has trained sum pretty rank horses to shoot off of.he did have sum he had to start out with a 22 revolver and them blanks yu buy at lowes for your concrete nail gun.the rest he just fired off and held on!he said yud be surprised how well they take it. he is closeing in on 80 yrs old so im not sure whether he just likes to be bucked off or likes the challenge.
