My husband passed almost 9 years ago and I haven't looked in the gun safe since, but with the world the way it is I recently purchased a couple pistols for my personal protection and decided I should inventory what rifles I had. That brings me here, 2 of the rifles I inherited are Remingtons. A 11-48 12ga shotgun and a Matchmaster 513T both of which are rather old (possibly 1954 & 1947) both of which my husband might have been inherited from his father or grandfather.

The 12ga, according to the downloaded owner's manual, should be able to hold 3 rounds. They call it a magazine, but there is nothing external, the rounds just get stuffed into the bottom of the carrier. Weird!! The 513 has a cute tiny little 5-6 round clip, having a hard time finding extras.

I know this is 3 months old, but I did not see an answer to finding extra magazines for the 513T.
I got reproduction replacements for mine at Brownells. If you want originals, keep an eye on eBay.
