Went into my local gun shop this morning and this was sitting there for a smoking deal - it just followed me home. Thought I'd better try it out so I loaded up some of my Lee TL 158gr SWC with 3.4gr of BE in some .38 special and tried my hand at 7 yards. The difference in "groups" (I used that term loosely) is one is a 6 o'clock hold and the other is a center hold. Now that I know it works time to try some .357s!
