I took the M4 out today for it's 1st break-in run... Shot a total of 95 2-3/4" rounds through it, starting with 40-rounds of 00-buck, then mixing it up with #9 1330fps, slugs, & more 00-buck. The weapon had only one failure-to-eject with one of the #9 rounds, when braced on the shoulder. I tried running a few rounds of the #9 and the 00-buck firing-off-the-hip, but all of them resulted in failures-to-eject.
I'm going to clean & lubed it tomorrow, and take it back out soon... Once broken in well, will these fire-off-the-hip OK? I'm assuming that today's off-the-hip issues were because of needing to be broken in more!?!?
Thanks,
K.
