Federal Large Pistol Magnum Primers #155 Box of 1000

Clear Product Overview

Federal 155 Primers (Large Pistol Magnum) are engineered to deliver a intense, long-duration flame flash required to ignite heavy charges of slow-burning ball and spherical propellants in large-capacity handgun cartridges. Utilizing Federal’s proprietary non-corrosive, non-mercuric priming formula, these No. 155 primers feature precision-formed cups designed for sensitive ignition even under light hammer strikes. Whether you are loading magnum hunting rounds in .44 Magnum or high-pressure heavy loads in .45 Colt, Federal #155 primers ensure instant combustion and reliable performance in demanding conditions.

Real-World Use Information

When loading heavy magnum handgun powders such as Hodgdon H110, Winchester 296, or Alliant 2400, Federal 155 Primers eliminate hangfires and unburnt propellant residue. Their responsive anvil construction makes them a favorite among revolver shooters who require reliable detonation in double-action and single-action handguns. The dimensional consistency of these cups ensures smooth feeding through progressive press feed tubes (Dillon, Hornady, Lee, RCBS) and clean seating into large pistol primer pockets.

Compatibility & Requirements

Cartridge Compatibility: Fits all standard large pistol primer pocket brass (.44 Mag, .45 Colt, .41 Mag, 10mm Auto, .454 Casull).
Equipment Compatibility: Seats cleanly using standard hand priming tools, bench tools, and progressive press priming assemblies (Dillon, Hornady, Lee, RCBS).
Safety Requirement: Always wear protective eyewear during handling, store primers in a cool, dry place away from heat sources, and strictly follow published load data when working with magnum primers.

Pros & Limitations

Pros:

Hot Thermal Flash: Sustained flame output ensures complete ignition of dense ball and spherical powders.
Sensitive Ignition: High sensitivity guarantees positive detonation across standard and lightened trigger mechanisms.
Clean Combustion: Reduces unburnt powder residue in revolver barrels and action cylinders.
Non-Corrosive Chemistry: Protects precision bores, cylinder gaps, and breach faces from chemical pitting.

Limitations:

Magnum Heat Output: Generates higher energy than standard large pistol primers; always reduce powder charge weights by 5% and work up safely when substituting into standard recipes.
Not for Small Pocket Brass: Designed strictly for large pistol primer pockets; cannot be used in small pistol pocket cases.

Frequently Asked Questions (FAQs)

Q: What is the difference between Federal #150 and Federal #155 primers?

A: Yes, Federal #155 primers are one of the most recommended choices for reloading .44 Remington Magnum with slow-burning powders like H110 and W296.

Q: Are Federal 155 primers non-corrosive?

A: Yes, Federal #155 primers use a modern non-corrosive and non-mercuric priming formula that will not damage or rust your firearms.

Phil From Grayson, GA – June 6, 2022

After waiting several months and having this item on my wish list I was finally able to purchase 5,000 primers. I have been using CCI primers for years not just in large pistol but also in small pistol and in rifles. CCI makes good stuff at a reasonable price, I will continue to use CCI and I would recommend this product to anyone who loves to reload ammo.
