PPU 556 M193 55gr FMJ 20

Product Description

PPU 556 M193 55gr FMJ 20 is Prvi Partizan’s M193 specification ammunition for 5.56 NATO and .223 Remington chambered rifles. Each box contains 20 rounds loaded with 55 grain full metal jacket bullets.

M193 refers to the original U.S. military ball cartridge specification for 5.56mm ammunition. It pairs a 55 grain FMJ projectile with a load profile designed for a 20-inch barrel and 1:12 twist rate, though it fires reliably in modern rifles with faster twist rates.

This Prvi Partizan load works for training, plinking, and range practice where you want dependable ignition and consistent point of impact without the cost of match-grade rounds.

What M193 Specification Means for Your Rifle

The M193 designation indicates a specific bullet weight and velocity profile originally developed for military use. Unlike newer M855 62-grain loads, M193 uses a lighter 55 grain bullet with a lead core and copper jacket—no steel penetrator tip.

This ammunition fires from both 5.56 NATO and .223 Remington chambers. Always verify your rifle is marked for 5.56 NATO if you are shooting 5.56 ammunition. The two chamberings differ in throat dimensions and pressure tolerances.

Barrel twist rate affects stability, but 55 grain bullets stabilize in virtually all common twist rates, from 1:12 down to 1:7. Faster twists may overstabilize light bullets slightly, but accuracy remains acceptable for general shooting.

PPU 5.56 Compared to Other Budget Range Loads

Prvi Partizan manufactures in Serbia and has supplied military and civilian contracts worldwide. The brand occupies the middle ground between bulk steel-case imports and premium U.S.-made brass ammunition.

PPU brass cases are boxer-primed and reloadable, unlike steel-cased alternatives that many shooters discard after firing. If you reload or save brass, this matters. If you shoot and leave, steel case costs less.

The 20-round box format suits buyers who want to test a brand before committing to bulk purchases, or who shoot occasionally and prefer smaller inventories. For high-volume training, consider our larger packs of rifle ammunition.

Frequently Asked Questions

Q: Is PPU M193 the same as standard 5.56 ammunition?

A: PPU M193 is 5.56 ammunition loaded to the original M193 military specification with a 55 grain FMJ bullet. It differs from M855 62-grain loads and civilian varmint or match loads, but it is fully compatible with rifles chambered in 5.56 NATO or .223 Remington.

Q: Can I shoot PPU 5.56 in a .223 Remington chamber?

A: You should only fire 5.56 NATO ammunition in rifles explicitly marked for 5.56 NATO. Chambers marked .223 Remington only have tighter throat dimensions and may generate unsafe pressure with 5.56 loads. Check your barrel markings or call 817-393-4000 if you are unsure.

Q: Does the 55 grain bullet weight work in all barrel twist rates?

A: Yes, 55 grain bullets stabilize in twist rates from 1:12 through 1:7. Faster twists like 1:7 are optimized for heavier projectiles, but they still stabilize 55 grain bullets adequately for general shooting and training.

Q: Is Prvi Partizan brass reloadable?

A: Yes, PPU ammunition uses boxer-primed brass cases suitable for reloading. Inspect cases after firing for signs of stress or damage, and follow standard reloading practices for 5.56 NATO brass.

Q: Why buy a 20-round box instead of bulk ammunition?

A: The 20-round format lets you test Prvi Partizan ammunition in your rifle before committing to larger quantities. It also suits shooters with occasional range trips or those who prefer rotating through smaller lots of different brands.
