I found my XCR settled right down at 25 grains WC735 under a 55gr fmj with magnum primers (my xcr beats on the primers pretty hard... punctures at starting loads with regular small rifle primers). By the looks of it this is a little above published maximums, so work up with caution. For me the load just settled right down at 25 grains... clean cases, smaller extreme spread/standard deviation and the best accuracy of the loads I tested. I have shot a couple thousand rounds of this load with no ill effects on the rifle or cases, but as I said, work up using caution.
EDIT: Forgot to mention, I load them on my xl650 and it meters beautifully.
