I have never had a failure to fire from light primer strikes with any of my Marlins when using a standard hammer or wolf aftermarket lighter spring. Palo Verde adjustable springs have given me some problems at first tell the adjustment was right.

 

I’ve had a FTF with a very light primer dimple in a couple of my Marlins over the years. The two piece firing pin kinda acts as a safety. You need to keep the pins and the inside of the bolt very clean and free of oil residue and buildup. I use a dry lubricant on mine and have not had a FTF in a number of years.

 

I got tired of the rear firing pin breaking. All the replacements I tried were new Rem/Marlin production and broke again quickly. I'm trying both types of one piece pin, titanium and steel, one in each 1894. Purchased from Longhunter. Both have over 5,000 rounds on each and never a worry. Stock hammer spring, I hate light primer strikes.

 

Hey rob42049, so do i

Yeah rob42049, me too. I had tried replacing the hammer spring with a stiffer (for lack of a better word) spring and didn't help so went with the one piece pin and have not had a problem since. I don't remember where i got the one piece pin as it has been two or three rears ago but that fixed it. It has been mentioned that the two piece firing pin was also a safety too and I knew that when i replaced it. Also kept the stock spring and all is well

 

You might try soaking your bolts in a mix of 50% mineral spirits and 50% your favorite lite oil, at least overnight.

 

I had light primer strikes/FTF in my Marlin 35 Remington with Remington 200 grain heads. Swapped out primers and used the same head and powder, everyone went bang afterwards!

I had the same problem with Remington 30-30 and 35 Rem ammo. Other brands all went bang on the same day. I used Remington Primers for quite a while with no problems.

You do not need to add oil to the Mineral Spirits. Just straight up MS. Soak over night. I sloshed my parts around then blew off excess with an air compressor. Poor mans ultra-Sonic cleaner.

 

I have never had a problem with my 336C in .35Rem or the 336C in 30/30.

The above is the 30/30: This is the 335C in .35Rem:

Both are great JM Marlins. I use YouTube for help since the issue may be 2 or more small issues.

 

Just curious, but you didn’t mention if you’re using factory or reloaded ammo. When it comes to problems such as you’re describing the more info you can provide, the better. This forum has a pretty good collective knowledge base, but the devil is always in the details and we want to steer you in the right direction.

I guess you mentioned me? I only use factory ammo as reloads are more work for me.

Just saying but I bought my guns and ammo a long time ago .These two rifles where $250.

 

I have a '51 336A in 35 Remington that gave me fits when I first got it.........FTF on nearly every round(Remingtons 200gr) of factory ammo.I was closing the lever pretty hard while chambering a round and always got a FTF.If I closed the lever gently it would go off consistantly.........When reloading I neck sized the fired cartridges and haven't had a single issue since..........Seems to me that those Remington cartridges had their shoulders pushed to far back and were sliding to far forward in the chamber for the firing pin to hit the primer ............I may be wrong in my analogy,but I don't think so
