They are very slightly shorter than the same batch of rounds with the flattened tip TMJ's loaded the right way around. I just realized after mulling over the "full" part of the acronym these aren't even FMJ's, these are real deal TMJs! I haven't chronoed the turned around ones vs. the normal ones but mixing in a bunch of both I couldn't discern from recoil which ones were the flipped ones. Only the hole-punch like hole told me. I think they're very close if not identical in the powder charge, especially since these were machine-loaded.Is oal the same between the forward and backwards loaded rounds? If those loaded backwards are shorter yonder's point on case capacity would be a possible issue, if anyone else ever finds this post in the future.
