I will soon be picking up a new to me 52-2. I intend to reload and already have a rcbs # 82031 mold 148 gr, wc ..but it has a little crown ? on top and not " a flush top" as some 38 sp. wc factory loads I have. Will my rcbs mold work in this md 52 ? or do I need to get a mold that will produce a flush top like factory rounds ? Thanks guys .. this forum is the best.
