i own one,
you need a mild load, otherwise your cases will be totaled coming out of the gun. I had to scale back from 46gr of BLC-2 with a 150 SST to a starting load of 45 GN because it was bending the rims and putting holes in the side of the cases on extraction/ejection.
With the new load (had to pull like 500 rounds) it cycles a lot better and the cases are reusable now (case necks are still bent but meh). I haven't done a good accuracy test with the reduced loads yet
