They were designed around the 124 nato but seemed to work okay with 115s also....the theory on my old P7 site at park cities tactical was that the heavier bullet worked it's way forward in the mag and by the last round it would feed too far upward and catch on the hood of the barrel..
Thank you for the information, Sip. Mine is dead nuts on with the 115gr. FMJ out to 25 meters.
