All the above is good advice, Greg, but I have found that when I get to missing such as you did, I simply try to relax, concentrate on the target, keep the gun moving and let things go as they will. It usually works for me and I start getting back to consistently breaking targets. BTW, this works on either the skeet field or the SC course. For me, anyway. Perhaps the fact that I shoot only a couple different guns other than my Beretta 687 on clays, and then shoot other guns only occasionally, may have a good deal to do with getting back in swing of things, so-to-speak.
Hope this helps. -- Ed
