Remington 783 6.5 Creedmoor Magazine Not Feeding? Troubleshooting & Replacement Guide
A Remington 783 in 6.5 Creedmoor that stops feeding a few rounds into a sight-in session is almost always a magazine problem, not a rifle problem - most often a fatigued spring, a tilted follower, or spread feed lips. Work through the checklist below before you spend money on parts, and you'll fix it once instead of guessing your way through two or three attempts.
How the magazine is supposed to feed
The 783 uses a detachable box magazine with a single-column feed presentation - rounds stack with the top cartridge centered under the feed lips. The short-action body used for 6.5 Creedmoor holds 4 rounds in factory configuration. As the bolt strips the top round forward, the case needs to clear the feed lips at a consistent angle so the bullet nose rides up the feed ramp instead of stubbing into the chamber mouth. That depends on three things working together: spring tension, a follower that tilts forward correctly as rounds deplete, and feed lips holding even spacing on the case rim. When one of the three fails, the symptom looks the same from the shooter's seat - a round that won't feed - but the fix is different depending on which one it is.
Diagnostic checklist
- Load 2 rounds and cycle by hand. If it feeds fine at 2 but fails at 4, suspect spring fatigue.
- Press the top round down with your thumb and release. It should snap back up crisply; a sluggish return points to a weak spring or grit in the housing.
- Look at the follower from the side while loaded. It should lean forward, not sit flat or tilt backward.
- Visually compare feed lip spacing against a known-good magazine.
- Insert the empty magazine and confirm it seats flush with an audible click, then tug down to verify it's locked.
Cause #1: worn or weak magazine spring
Springs are the most common failure point because they're the only part under constant load. A spring that's spent years compressed can lose enough tension to slow follower return speed, which shows up first on the last round or two in the stack - if your rifle feeds rounds 1-2 fine but chokes on round 3 or 4, that's a textbook weak-spring signature. ARM doesn't sell magazine springs as a standalone part - we build complete factory-pattern magazines. If your diagnosis points to the spring, the reliable fix is a full replacement magazine, not a generic aftermarket spring for a part we don't sell separately.
Cause #2: follower tilt and nose-diving
A follower cut for 6.5 Creedmoor accounts for that cartridge's shoulder angle and case head, different enough from .308 Winchester that cross-using magazines between calibers causes chronic tilt problems. Signs include the bullet nose visibly dipping below the feed lips, or the round catching the bottom edge of the chamber instead of riding up the ramp smoothly. This isn't something you can bend back into spec reliably - a magazine with a tilting follower needs to be replaced.
Cause #3: feed lip damage and spread
Feed lips are the two tabs at the top of the magazine body that grip the case rim and control release angle. They take abuse from being dropped loaded or jammed into a mag pouch too hard. Spread lips let the case rim slip forward prematurely, causing a double-feed or stovepipe jam. Chips or cracks at the lip edge mean the magazine needs replacement - bending metal lips back into spec with pliers is a temporary fix at best.
Cause #4: magazine fit in the well
Sometimes the magazine feeds fine on the bench but fails in the rifle because it isn't seating flush against the receiver. Check the magazine catch notch for wear or burring from repeated hard insertion - that rounds off the notch over time and lets the magazine sit slightly low in the well, which shooters often misdiagnose as a magazine problem when it's a rifle-side fit issue.
Rule out ammunition first
Not every feed failure is the magazine's fault. Overall cartridge length varies between ammunition brands and can push a round outside the magazine's designed envelope, especially with long-for-caliber 6.5 Creedmoor match bullets. If your magazine feeds standard hunting ammunition fine but chokes on a specific match load, test with at least two factory loads before assuming a parts failure.
Preventive maintenance
Clean the magazine every couple hundred rounds: strip it down, wipe the spring and follower with a dry cloth, and clear powder residue and lint from the feed lip channel. Avoid storing magazines fully loaded for months at a time. Rotate between two magazines for any rifle you shoot regularly - it halves the cycle count on each one and gives you a backup if one develops a problem mid-season.

Frequently asked questions
Why does my Remington 783 6.5 Creedmoor magazine not feed the last round?
The last round sits highest against the feed lips, where spring tension is weakest. A fatigued spring or a follower that has lost its forward lean often can't push that final round up with enough force.
Can I fix a Remington 783 magazine spring instead of buying a new magazine?
ARM doesn't sell magazine springs as a standalone part - we build complete factory-pattern magazines. If diagnosis points to the spring, a full replacement magazine is the reliable fix.
How do I know if my 783 magazine feed lips are damaged?
Compare them side by side with a known-good magazine. Spread, uneven, or chipped lips let the case rim slip forward or tilt before it reaches the chamber.
Is the Remington 783 6.5 Creedmoor magazine the same as the .308 magazine?
Both are short-action magazines and share the same body length, but internal geometry is tuned to each cartridge's shoulder angle and case taper - they are the same magazine part, rated for .308 Win, .243 Win, and 6.5 Creedmoor.
What causes a Remington 783 magazine to fall out during recoil?
A worn or dirty magazine catch, or a latch notch damaged by repeated hard insertion. Clean the catch first, then inspect the magazine's catch notch for wear.
Work through the checklist above before buying parts. If your inspection turns up a bent body, spread feed lips, or a follower that won't sit right, replace the magazine with a purpose-built 6.5 Creedmoor short-action unit rather than repairing it a third time.
