220 Grain 300 Blackout Ammo Guide

The Fenix 220 grain option is an FMJ training load sold in a 100 round pack. Fenix explicitly identifies it as subsonic and publishes 1,000 FPS. Those facts make grain, projectile, category, quantity, and published velocity the useful comparison fields. The neighboring 190 grain product is also explicitly subsonic and sold in 100 rounds, but it uses a Hornady Sub X projectile and is categorized as defensive ammunition. Compare the two product cards, then view the 220 grain product details for current stock, price, and the full product description.

When to use the 220 grain page

Choose the 220 grain product when you want the listed FMJ training option rather than the 190 grain Sub X product. Fenix states that the 220 grain load was tested in several rifles with barrel lengths from 8 to 10.5 inches, with and without suppressors. The same description cautions that rifle setups vary and may require changes to gas settings or buffer weights. Do not treat that test range as a guarantee for every configuration. Review the complete setup note on the product page, check current availability, and use the subsonic collection to compare the 190 grain alternative.
