What works for me on steel is to paint the gong/steel pre shooting. I love it cause I can instantly see where I hit, 4 me I like to know where I hit it not that I hit it.
Easy to measure groups this way as well.
Works 4 this kiddo
Dober
I do the same thing, Dober, I just don't usually get out the tape measure or caliper and actually measure the group sizes. Five hits on the center of the plate gives me the warm fuzzies even if I don't bring the caliper with me.
