My Dad and Uncles all shoot an excalibur w/ 200# draw with 125 gr. spitfires with one problem but no premature opening from the shot and great arrow flight...the only problem is getting blood on your boots and legs from the massive blood trails!!!
My buddy uses swhackers out his excaliber and loves them.I have seen the holes and it looks like they were hit with a axe.Some brands can open in flight out of these hard shooting machines.
