Obviously, at longer ranges, those impact points might crossover due to the flatter trajectory with the higher velocity, though, but I haven't ever tested this out as mine only tend to get used at short range.

The '45 is addictive and I don't want sessions to end quickly.

And another bonus.....they smell fantastic.
It was the low impact point at high power that surprised me all those years ago when i purchased my first 45.
