I told them we should have taken a video of it.... We have actually done our own little torture test on the X9, we have had a 1000+ rounds through our demo one now, assorted loads and brands. Only thing we found that won't feed reliably is either low recoil ammo or some of the lighter target load ( 7/8 oz ). They would cycle but it could be hit or miss. So running a #8 1 1/8oz or higher was chugging along just right.
