Feed issue on Marlin 25, bolt scrapes bullet



Log in to see fewer ads
Folks,
I've had my Marlin 25 since 1982 (first gun). If this is a known problem that's been posted, I apologize now.

I've long had a problem that when the bolt moves forward to chamber a round, it scrapes the round that's below the chambering round, and takes off a piece of the lead bullet as the round chambers. This happens for all but the last two rounds in the 7rd mag. I recently purchased a new mag for it, and it does the same thing as the original mag.

I can lean on the mag (pulling it down and forward a bit, as there is some play in the mag well as you know) and sometimes that helps it cleanly chamber. However, that's not a good fix and I'd like to fix this. I've never worked on this rifle at all. I can't remember if it did this initially, but it's been doing it for years.

Thoughts?

It sounds as though the magazine needs to nose forward so that the rounds don't point upward as much. The 25 is similar to the 780, 80, Glenfield 20, as the all use the same magazine. The magazine floor plate that the magazine is inserted through may move just enough to remedy your issue. If your floor plate will move backwards it may help.


My wife has a Marlin 780 that magazine was a pain to remove, and the magazine floor plate needed to move ever so slightly, and now it comes out easily.

I have seen 10-22's and bolt guns scrape the round, but they were doing it when they were ejecting the spent round. The bolt had a sharp edge on the bottom that raked the top round in the mag during ejection.

Polish the bottom of the bolt and make sure that the bottom front edge is slightly rounded. If the edge is at all sharp, it will shave off some lead of the round that is at the top of the magazine as the bolt passed over it.

Out of curiosity, what did you use to do that?

I have done it this way
Use a Popsicle stick as a flat backer with fine emery paper to take the rough surface/ round the fount edge down some..then use 600-800 black automotive wet/dry sand paper to polish also using the flat backer..a piece of leather belt also works good as a flat backer

Hope this gets you there!

Used 600 grit wet or dry paper wrapped around a small flat file.

Probably not the problem but does the same thing happen with different ammos?

Curious what the OP has figured out. Seems the thread is forgotten.
