Mossberg M44US Light Primer Strikes

[Augi]

I recently took my new CMP M44US to the range and with certain ammunition I am getting failure to fire due to light strikes.

Using American Eagle 38gr. hollow points I got maybe 6 light strikes out of 100 rounds fired. After re-cocking, all rounds fired on the second try

Not a single CCI CB would fire in the rifle no matter how many times I tried. The brass must be harder because the pin strikes are not nearly as pronounced as on the American Eagle cases.

I have never had a light strike in any other .22 rifle and I have fired thousands of these rounds. I fired all of the CBs right afterwards in a different rifle, so the rounds were not duds.

Even after disassembling, cleaning and oiling the bolt, the CB's still will not fire.

Does anyone else have this problem? I am thinking about a stronger firing pin spring, but I also want to know if this is a common thing.


Edit: 38gr. ammo not 36

I've had my "US PROPERTY" marked M44 for about 5 years, long before the CMP ones were released. I've never had any problem with mine other than misplacing the magazine "pin" or whatever you want to call it.

I'm using this ammo below on my newly arrived CMP M44US, I had one round act like you describe so far out of about a 100 or so rounds of the box I have.

Model American Eagle
Caliber 22LR
Grain Weight 38Gr

I'm also having a sticky extractor issue - i'll prolly tear apart the bolt this weekend when I get a chance....
