Bad .22 ammo or malfunctioning gun?
 
I was out with a Marlin 99M1 this past weekend and ran a few different types of ammunition through it- Wolf, Remington, and Federal Bulk. Each type of ammo ended up producing a dud almost once per magazine (8 round tube). Always had a hammer mark, but they just didn't go off.

I know those aren't premium manufacturers, but is that typical of .22 ammunition or am I looking at a problem with the rifle itself? Maybe a hammer spring?

I've had pretty good luck with Federal bulk but Remington has always been terrible for me. With a dud per mag I'd suspect some type of mechanical problem though. Not knowing squat about rifles, I can't help but in a handgun I'd be looking at a weak mainspring or crud in the firing pin channel...

Could be a kinked recoil spring - my 99M1 has one. Too easy to accidentally kink it when removing/reinstalling for cleaning! Mine will have an occasional misfire too. Mine also won't reliably cycle with the mag tube full - use one less round, works fine.....

Thanks for the info NG and Bigdog. I noticed the same thing about the mag tube, 7 seems to be the magic number. I had a fair number of stovepipes as well, but I seem to remember reading about that being a common problem with these rifles.

Bigdog, have you done the replacement feedthroat conversion? I'm trying to decide if that might help at all.

Bigdog57 10-21-2010 05:17 PM

No, I haven't done that yet. May think about it though. Fun little rifle - excellent 'bunny buster'!

The 1st thing I would do is clean it real good & oil it. That should take care of most of your problems.

YES YES YES. Bulk Ammo Esp. Stay away from Hollow point in bulk in semi auto's. Nuttin but burnt powder and residue.:eek: Keep it Klean.:)

sounds pretty typical for .22 ammo. i have 3 different .22's and they are all extremely well taken care of and cleaned, but i get misfires maybe 15-20/500 or so.

Your gun is a dressed up model 60. The main cause I have found is dirt. Over lubing will hold dirt. Mine hates bulk ammo. I can shoot Winchester Wildcats, Any kind of Aguila, CCI, but it hates cheap bulk ammo. I would also clean the ammo tube.

I have definitely read to stay away from HV ammo, but I'll see what I can find for higher quality without going HV.

Thanks everyone.. I'll be giving it a thorough cleaning. Should be out again with is this weekend, I'll report back if it's still fishy.
