Overloading a magazine increases the likelihood of which issue?

Explanation:
Overloading a magazine disrupts the way rounds are presented to the chamber. The magazine spring is designed to push a precise stack of cartridges up so the top round feeds smoothly into the chamber. When you cram in more rounds than the magazine is meant to hold, the spring becomes excessively compressed and the follower and rounds can bind or tilt. The top round may not present correctly to the feed lips, and the bolt may not strip it cleanly. That misalignment leads to failures to feed or other feed-related jams, which is the most likely issue you’ll encounter. The other options don’t fit because accuracy depends on consistent, reliable cartridge presentation, not on simply having more rounds in the mag. Faster reload times aren’t gained by overloading; in fact, they’re often slowed as you try to seat extra rounds. Recoil control isn’t meaningfully improved by extra rounds; the weapon’s dynamics are governed by weight, gas operation, and overall cycling, not by the magazine being fuller.
