I use a Redding Boss for case forming and small lots of ammo. (read .243 and .308) Good, solid machine that has no faults. Not terribly expensive either. While I have two 550's (one set up for small primers and another set up for large primers) I would not want to be without the Redding.
Great match, well run, good targets, great range. Come and try handgun silhouette. You don't need anything special, any .22 handgun will do.
IN IHMSA, you don't have to walk down range to see if you hit the target; if it falls, you did great, if it did not fall, go for the next one.
