Alright guys, so I have always practiced before the hunt with field tips. I get really solid with my groupings and then when I switch to broad heads, Groupings are obviously going to change. I've recently switched to wack'em broad heads and they're awesome. Groups are tight and beautiful, but should I always just practice and tune my bow with broad heads? What do you guys use while practicing in the summer? Because 100 grain practice heads and 100 grain wack'ems don't fly the same!
