Been out of the loop awhile, but recently purchased and older pre safety Marlin 336 in 30-30, my first lever gun, bought it on the cheap, for $150, ramline stock, some light pitting on the ouside. Full disassembly, cleaned scrubbed and oiled all parts, punched and swabbed bore (nice and clean), reassembled, function check, everything working smooth.

Took her out with Winchester Super X 30-30 WIN 170gr , open the action, put one round in the chamber, loaded 3 in the magazine tube. First round fired fine, cycled the action, next round chambered, fire, cycle open action, FTF. after pushing around gingerly with a slim screwdriver for a while I found giving a slight nudge on the rear of the round, maybe 1/8th of an inch the lever will close and the round will fire.

However, after numerous loading, this Fail to Fire sometimes happens to the first round, or second, or third, or 4th round 20% of the time. I make sure I fully cock and return the lever, I have tried working the action quickly and slowly, holding the rifle barrel up, forward, barrel down, and canted, the random jam happens anyway I try.

My best guess is that the next round in the magazine tube is pressing the round to the rear in the loading elevator? (dont know what to call it) and that 's where it gets stuck and by gingerly leveraging on the back of the round pushing it forward it will loosen and load.

Need help, do I need to replace a part? This is my first lever gun and totally in the dark about the finer tuning adjsutments to fix this. Any help would be greatly appreciated.

I am as dyslexic as they come about mechanical function & such, but I would post this question over at Marlin Owners in the 336 section:

So THAT'S why it was so inexpensive! Did you happen to buy it from a store? If so, take it back and see what they say. I would also try a different brand of ammo, just for kicks. If all else fails, consult a qualified gunsmith. Good Luck!

Check to make sure all the screws are snug...I have heard the loading spring screw can cause feeding problems.

I would suggest checking the two screws at the front of the trigger plate. One is short and the other long. If you reverse them, you can end up with a situation similar to this...

Hope this helps,

Matt

Abel - gonna try posting over there, as soon as I get the time to register

Dr. Sandman - alas no store, classifeds. will probably try a different brand maybe something with a different OAL.

Krimmie - may try adjusting the loading spring screw, but I am not sure what that is. LOL

ECVMatt - check the screws, longer one is upfront underneath and the shorter one is on the side of the receiver

will keep you updated.

Also make sure the "loading gate" screw is tight. That screw is the one closest to the loading gate on the same side of the receiver. My Mdl 30AW gets cranky about feeding if that screw becomes loose.

The loading gate screw is the screw that secures that springy flap where you push down on to insert the powerful and mighty 30-30 cartridge into the magazine. Its behind the gate.

from your description I can't tell what's going on, but I'll buy it off you for $150 and find a way to make it work :)

but any time I hear about a failure to feed on a marlin using round point ammo I think of the "marlin jam". (google it)

The loading spring/gate screw is the same thing...see part 46 in manual. Also page 9 of the manual makes reference to keeping this screw snug.

Well after my initial purchased as I stated in OP, I did a complete dissassembly, clean oiled, and polished some key areas, and still the dreaded "Marlin Jam" Did some Google Fu and learned that alot of times the carrier/loader tray digs a groove into the lever, which alters the timing of when the next round is stopped or loaded into the carrier. There is a fix of welding up the low groove that was created and sanding it down to the original thickness. Well I just found a new lever on ebay for $9 and now she feeds like a dream. Thanks for all the help guys!

Nice work! I have a 1971 336C that I put a Ramline black plastic stock on. It is my favorite rifle. I put a 2-7x32mm Nikon on top and she groups the Hornady LE very well. I have a hard time picking between her or the 336C 35 Rem when I head out for deer.
