Loaded and fired the Lyman load of 4.0 gr at 1.075 and 4.2 gr at 1.100. Neither cycled the action sufficiently to eject cleanly and allow feeding of the next round. Will continue up slowly with N340 and also try the VihatVouri recommended N340 starting load for FMJ/FP of 5.3 gr at 1.142 OAL. Thanks to you all for your advice and to Sieger for the comment on SR4756, which may be the ultimate winner.
