At my most recent WB match here in Australia there were 2 stages where a tactical reload offered a benefit.... but I suspect I was the only shooter at the match to actually do so...on both at least. I feel perhaps far more comfortable with the concept as an IPSC shooter of some years experience. Talking to others at the match they generally saw the downside of doing something they were NOT used to...and so refrained.
I think its a great addition (as is the 7 rd mag useage after all, that's what the gun was designed for , right?) and that the game is just getting better. Yes, the RO needs to be on the ball...but that is nmot new, especially in WB.
