I've been reading through the 102 reliability thread in the MBR section and after hearing that there are some 102's out there that seem to be a lot more sensitive to ammo than some others I'd like to suggest that whichever rifle is selected for this test that the owner already has a couple hundred rounds through it and it has proven to be reliable with most types of ammo. I would hate to get it to Jerry and have him struggling with cycling issues rather than concentrating on load development and accuracy testing.
