Old Mossberg 352K help

[MossbergSpecialPurpose]

Hi guys,

my dad passed down an old Mossberg 352K semi auto .22 rifle that his dad bought him when he was a kid. This gun is in great shape, other than the odd jam once in a while. anyway, quick question.

I replaced the firing pin with a new one. Now the gun only shoots about every second round. I will manually eject a round when it does not fire and look at it. They have a slight indent on the casing. If i put the non-firing round back into the rifle it will shoot the second time around. Is this due to the spring being weak or something?

I might put the old firing pin back in. I replaced it due to the above mentioned problem before, but with the old pin in it it fired alot better.

Try different ammo, and see if that clears it up. Some Rem ammo is bad for not lighting up. New pin might also be shorter than the original. Other than that, check to see if the striker (hammer) travels freely without binding...

Make sure there aren't any burrs on the new pin which may be hampering movement, and dirt in the firing pin channel.

I have a Mossberg 352KA which had the same stumbles. A real good cleaning ( took bolt out and scrubbed the bolt chamber with a brush) and oiled well along with a new firing pin sanded so it slid easily in the slot. Problem cured . It eats any ammo now. Rem. ammo seems to have the "misfire- nofire" problem in all my .22s.
