I have one of those lyman universal trimmers. The thing has never worked quite right since new. You cannot get the brass to stay put.. The little cam arms are worn pretty bad. I bet I havent trimmed over 1.5k brass with it. I have tried switching sides with the cam arms-They are just junk. Parts are on order from lyman. Great idea with the universal chuck but terrible quality on parts. Anyone else have the same problems???
