IMR 4227 smokeless gun powder canister for magnum handgun and cast bullet loads

Product Description

A Fast-Burning Specialist Powder

IMR 4227 fills a distinct niche in the IMR lineup. Unlike many IMR powders built for standard rifle cartridges, this fast-burning powder is purpose-suited for magnum handgun cartridges and cast bullet rifle loads, giving reloaders a specialized option for applications that need a quicker burn rate.

Built for Magnum Revolvers and Cast Bullets

Reloaders often choose IMR 4227 for large-capacity magnum revolver cartridges. Because it burns fast relative to typical rifle powders, it suits these high-pressure handgun applications well. In addition, cast bullet shooters frequently use IMR 4227 in rifle cartridges loaded with cast rather than jacketed bullets, where a fast-burning powder helps reduce leading and pressure spikes.

Consistent, Specialized Performance

IMR manufactures 4227 to the same rigorous standards found across their full powder lineup. As a result, reloaders working in this specialized niche get dependable, repeatable results, whether loading magnum revolver rounds or cast bullet rifle loads.
