Fail to pick up a round?

[CryingWolf]

Story:
Buddy and I along with Buddy's wife are out shooting.

Equipment:
Buddy's gun is a stock Smith and Wesson M&P15 and brand new P-Mags

Ammo:
Wolf Steel Case 55gr FMJ

Wife, who is small in stature, shoots two shots and the AR seems to short stroke with a fail to pick up a round from the mag. Repeat a few times.

Buddy shoots the rest of the mag no problems; I also shoot a mag with no problems

Wife again two shots and then a click as before; but both Buddy and I do not have these problems.

Does anyone know what could be going on?

She is not holding it tight against her shoulder, creating the semi auto rifle equivalent of limp wristing.

+1 Most likely the problem along with the lower pressure wolf. You could try some 5.56 ammo with her holding it like she did before just to test it out.

Several things play into this. As Thomas mentioned, the low powered Wolf is a big contributor, that combined with a stiff recoil spring and the rifle moving with the recoil impulse prevent the bolt from traveling far enough to the rear to cycle completely. I didn't know it was possible to "limp wrist" a rifle until I started spending more time behind the firing line as an RSO than on the line and saw it happen.

Wolf is weak, add a weak shooter and you get short strokes.
