Marlin Rimfire Magazine Troubleshooting Guide
A Marlin rimfire magazine that stops feeding mid-session almost always traces to one of three things: a spring that's lost tension, feed lips that have spread past spec, or grime built up on the follower rails — not a broken rifle. Work through the checklist below in order and you'll isolate the cause before you spend money replacing the wrong part.
It happens at the worst moment — three rounds into a squirrel hunt, or halfway through a long range session, the bolt closes on nothing. No round presented, no stovepipe, just a dead click. That's a magazine reliability problem, and it's one of the most common issues we hear about on Marlin rimfires, whether it's a 795, an 882, or the classic 780/25/20/80 pattern.
Why rimfire magazines fail more than centerfire boxes
A .22LR round headspaces on its rim, not a case shoulder, and that rim is thin and inconsistent lot to lot, especially in bulk promotional ammo. Centerfire magazines like those on a Remington 783 feed a round with a stiffer case wall and a fixed shoulder reference, which is far more forgiving. Rimfire feed lips have to control a round that wants to tip, roll, and catch on a rim edge that varies box to box. Add in the sheer cycle count — a rimfire shooter burning a few hundred rounds in an afternoon cycles a magazine spring far more in one outing than most centerfire hunters do in a season — and it's clear why a rimfire magazine should be treated as a wear item, not a lifetime part.
Failure to feed: the most common complaint
The bolt closes on an empty chamber even though the magazine reads as loaded. In almost every case, one of three things is happening: the spring has lost tension, the follower is hanging up on a burr in the body, or the feed lips have opened past spec.
Start diagnosis with the simplest test: load the magazine to capacity, then to half capacity, and try both. If it feeds fine at half capacity but fails at full capacity, that points to spring tension — a fully compressed spring needs the most force to push the stack up, so that's where a weak spring shows first. If it fails at any load level, including a single round sitting visibly crooked, look at the feed lips and follower tilt instead.
Double feeds, bent feed lips, and stovepipes
The magazine tries to push up two rounds at once, or a fired case doesn't clear before the next round starts feeding. This almost always traces back to feed lips spread wider than factory spec, usually from repeated hard loading, forcing rounds past capacity, or dropping a loaded magazine on a hard surface. Feed lips very rarely hold a field repair — pinching them back with pliers is a temporary fix at best. Replace the magazine rather than trust bent-and-corrected lips in the field.
Magazine won't drop free from the well
A magazine you have to yank or wiggle out is a different problem from a feeding issue. It usually comes down to a burred or dented body, a bent catch tab, or grime built up along the guide rails. Wipe the body down and run a thumb along both rails feeling for a raised burr or dent. If the body is clean but the magazine still binds, check the catch tab where it engages the receiver — a tab bent even slightly will drag on every insertion. A cracked or chipped tab means the magazine needs to be retired.
Spring fatigue: testing tension the right way
Spring fatigue is the quiet failure — a slow decline over a few hundred rounds until the magazine won't push the last round up. The hand test: load to capacity, press down on the top round with your thumb. You should feel firm, even resistance the whole way down, and the follower should snap back immediately when released. A spring that feels mushy or bottoms out with little resistance has lost enough tension to cause feed problems under capacity.
The single biggest thing you can do to extend spring life is stop keeping one magazine loaded indefinitely — rotate between at least two magazines so no single spring sits compressed for months. Since ARM builds the spring, follower, and feed lips into one complete magazine rather than selling parts separately, once a spring has genuinely fatigued, the fix is a full replacement magazine.
Follower tilt and why bulk-pack .22LR makes it worse
Follower tilt happens when the follower catches at an angle instead of rising square. Bulk-pack .22LR is manufactured to looser tolerances than premium ammunition — rim thickness can vary by several thousandths of an inch lot to lot — and that variance changes how each round loads pressure onto the follower. If a magazine is "randomly" unreliable, fine one session and jamming the next, switch to a premium round like CCI Standard Velocity or Federal AutoMatch for one full test session before condemning the magazine.
Cleaning and lubrication
Rimfire ammunition is dirtier than centerfire — bullet lubricant combined with unburned powder builds residue inside the magazine body faster than most shooters expect. Strip the magazine down every few hundred rounds of regular use: remove the floorplate, spring, and follower, and wipe every surface with a dry cloth or nylon brush — never a wire brush, which scratches feed lips and accelerates wear. Solvent is fine for the body but should be fully dried before reassembly. On lubrication, less is more: a single drop of a dry, non-gumming lubricant on the spring and a light wipe on the follower rails is enough. Oversaturating with oil collects powder and grit into a paste that gums up follower travel.
Repair or replace?
If a magazine is failing only under full capacity load and passes the hand-tension test with mild softness, cleaning and a period of lighter loading is worth trying first. If the feed lips measure visibly out of spec, the body shows a dent or crack, or the magazine has already had feeding problems resolved once and is failing again, replace the whole unit. A magazine that fails once every 50 rounds needs replacing now; one that fails once every few hundred rounds is worth a clean-and-lube cycle first, since intermittent failures at that rate are more consistent with grime than mechanical wear.

Frequently asked questions
Why does my Marlin rimfire magazine keep failing to feed?
The most common cause is a weak or fatigued spring that no longer pushes the follower high enough to present the next round. Bent feed lips and a dirty magazine body are the next two most likely causes. Test with a known-good magazine before assuming the rifle itself is the problem.
Can bent magazine feed lips be fixed?
You can sometimes bend feed lips back into rough alignment with pliers, but the metal has already been stressed and rarely holds spec long-term. For anything you rely on in the field, replace the magazine instead.
Does bulk .22LR ammo cause more magazine jams than premium ammo?
Yes. Bulk-pack .22LR has looser rim and case tolerances than match or premium ammo, which increases follower tilt and double-feed rates. If you're chasing a jam, switch to a premium brand for one full range session before condemning the magazine.
Should I store Marlin rimfire magazines loaded?
Short-term storage loaded is fine, but leaving a rimfire magazine loaded for months accelerates spring fatigue. Rotate loaded magazines periodically and cycle the spring.
How do I know if my Marlin magazine needs replacing instead of cleaning?
If cleaning and light lubrication don't resolve failure-to-feed after two range sessions, or you can visibly see gapped or splayed feed lips, replace the magazine rather than repeating the same clean-and-hope cycle.
Match the replacement to your exact model and caliber — fit tolerances differ enough between a 795 and a 982 to matter — and get back to a magazine that feeds every round the same way.
