Federal Large Pistol Magnum Primers 155 — Box of 1000 (10 Trays of 100) — Bulk Ignition for Heavy Pistol Loads

Federal 155 Large Pistol Magnum Primers give handloaders a proven option for heavy magnum handgun loads. For that reason, many reloaders reach for a hot magnum ignition source when building near-maximum charges. Additionally, dense propellant charge burn lights slow powders evenly. Consequently, this duty grade caliber choice performs well under sustained high-volume use. Finally, buyers who want bulk box reloading savings find real value in this case.

Federal 155 Primer Case: Extra Spark

Magnum charges need more than a standard primer can deliver. A hot magnum ignition source lights dense powder charges reliably across cold and warm conditions alike. Reloaders working near maximum loads notice fewer ignition-related issues.

Federal 155 Primer Case: Built for Slow Powders

Dense propellant charge burn matters most with slow-burning magnum propellants. Federal formulates this primer’s compound for consistent burn-off across the charge. That consistency shows up as tighter velocity spreads on the chronograph.

Federal 155 Primer Case: Duty-Grade Dependability

This duty grade caliber choice holds up to repeated use at the range and in the field. Reloaders working up loads for the Remington Large Pistol Primers #2-1/2 often keep both standard and magnum options on the shelf.

Federal 155 Primer Case: Frequently Asked Questions

How should I store these primers safely at home?

Federal 155 Large Pistol Magnum Primers belong in their original packaging, away from heat, sparks, and open flame. Primers are sensitive to impact and friction, so keep them in a cool, dry cabinet. The NSSF safety page offers guidance on storing reloading components.

Which cartridges typically use this primer?

Federal 155 Large Pistol Magnum Primers fit large-pistol magnum cartridges like .44 Magnum and .454 Casull. Reloaders working up loads for these cartridges sometimes also test the Winchester Large Pistol Primers #7 for comparison.

When should I choose this over a standard primer?

Federal 155 Large Pistol Magnum Primers suit charges that a standard primer may not ignite consistently. Always follow published load data rather than substituting primer types on your own. Magnum primers are not interchangeable with standard ones in every load.

What quantities are these primers sold in?

Federal 155 Large Pistol Magnum Primers ship as a box of 1000, split into 10 trays of 100 for easy handling. Liberty Anno Supply lists available pack sizes on this product page, with pricing updated regularly.

How long can I keep these primers before they go bad?

Federal 155 Large Pistol Magnum Primers remain reliable for decades when stored properly in a cool, dry, low-humidity environment. Rotating older stock to the front helps maintain consistent ignition over time.
