Crossbow expandable heads are hardser to open than vertical bow heads and a little larger diameter where they but up to the insert to match the diameter of bolts. I shot a couple Rage for compound bows years ago and the blades opened before leaving the crossbow, made for some eratic flight patterns. Just stuck with 125gr G5 Montechs for years after that.

You shouldn't have a problem shooting them out of a xbow unless your xbow shoots 400 or faster. I use the standard spitfires in my xbow and it shoots 350 fps and I've never had an issue. I dont shoot them numerous times into targets as this can weaken the retainer on them. They made practice tips that shoot exactly like the broadheads
