Oleg (and others) - What I currently do is a JHP in the pipe, AND one more JHP to top the mag off, then followed by ball. Reason being is, even if reliability is your concern, chances are extremely low that a JHP topping the mag will not feed, due to its already being popped all the way up, if that makes sense, but the third round (second in the mag) and following could be a potential feed concern if a wide-mouth JHP and slide velocity is so high as to not give it time to pop up. Having said all that, I think I'm going to switch to 100% ball, just for simplicity and costs sake, at least in my .45, because of the information I've been getting that expansion doesn't occur anyway in JHPs unless conditions are optimal. I used to carry mags with say, 7 JHPs, followed by 3 heavy balls, on the theory that if 7+1 JHPs don't stop your attacker, then you MUST be having a penetration problem. Did I just type "heavy balls" - there's one medical condition I've not had - yet.
