    What We Know

    Each upper has been test fitted and fired. As with all firearms, these shotgun uppers must go through a break-in period — Additionally, .410 shotshells are notoriously inconsistent in size.

    Based on our test firing, it is recommended that Federal T4129 Target Gold Medal Plastic 410 Gauge 2.5" 1/2 oz 9 Shot be used for the break-in period.

    Additional .410 Shotshell Recommendations

    Due to inconsistencies in the length of .410 shotshells, the following parameters are recommended:

    • For best results, use shells 2.25" in length
    • Use .410 shells with a minimum of 1200 fps
    • Use shells short enough to be easily loaded into the magazine(s)
    • Do not try to exceed the magazines listed capacity
