Condition and Equipment Used. Firearm: Winchester 9410 2.5 inch 410 shotgun with a 24inch cylinder bore. Range: 25yards to target and phone books Targets: For chronograph was simply targets for aim, all shot were pumpkin on a fence post. The phone books were three Cleveland phone books taped together with several wraps of duck tape and then soaked overnight in bucket full of water. Redneck ballistic gel. Where far from a perfect target wet phone books do usually cause bullets to expand and makes slug recovery fairly straight forward. Conditions: Beautiful morning, sunny and about 72F little or no wind. Chronograph: Alpha Chony with passive sky screen and remote interface (not in picture) |

Chrono Testing 5 shots Low Velocity:1809fps Hight Velocity:1827fps Average velocity: 1817fps Extreme Spreed:17.75 Std. Deviation:6.32 Manufacture Spec: 1830fps Measure Mass: 96.1gr Manufacture Spec 1/5oz (87.5gr) Calculated Muzzle Energy: 704.3ft-lbs Notes: Very consistent velocity. Also probably the tightest grouping slug fired from my Winchester 9410. |

Impact with wet phone books Penetration: ~2.5inches These were the shallowest penetration of all the slugs. As you can see in the pictures they made a very nasty entrance hole and were stopped at the about the back cover of the first phone book. |

Slug 1: 96.5gr (100%) Slug 2: 95.7gr (99%) Notes: Slug 1 actually weight slightly more than the sampled slugs I had weighted. Just a few tenth of a grain but this indicates that there may be some varability in Remington slug manufacturing. The slugs broke up pretty good on impact but had penetrated very straight into the phone books. |

Chrono Testing 5 shots Low Velocity:1792fps Hight Velocity:1917fps Average velocity: 1855fps Extreme Spreed:124.0 Std. Deviation:44.84 Manufacture Spec: 1830fps Measure Mass: 92.8gr Manufacture Spec 1/5oz (87.5gr) Calculated Muzzle Energy: 708.9ft-lbs Notes: The lightest slug tested and the worst for velocity consistency of the three unmodified loads tested. |

Impact with wet phone books Penetration: ~3.0inches These were the second shallowest penetration of all the slugs. As you can see in the pictures they made much smaller entrance holes compared to the Remington Sluggers and were stopped just into the second phone book. |

Slug 1: 90.9gr (98%) Slug 2: 91.7gr (99%) Notes: These slugs expanded the poorest, as you can see from the pictures they broke into two pieces and expanded very unsymmetrically and thus their penetration sort of deviated as they went into the phone books. |

2.5 inch shell  5 shot group at 25 yards (click to enlarge) |
Chrono Testing 5 shots Low Velocity:1714fps Hight Velocity:1742fps Average velocity: 1728fps Extreme Spreed:27.64 Std. Deviation:10.77 Manufacture Spec: 1775fps Measure Mass: 109.0gr Manufacture Spec 1/4oz (109.4gr) Calculated Muzzle Energy: 722.5ft-lbs Notes: Good consistent velocity and the heaviest of the true foster slugs tested. Unfortunately the worse grouping out of my Winchester 9410. Also note the wad in the lower right hole in target spot. Also in the extreme right bottom you can see were another one of the wads went through the target. I think this heavy plastic wad Federal uses make be the reason the accuracy suffers, likely cause by the way the was and slug separate at the muzzle. |

Impact with wet phone books Penetration: ~4.0inches These slug penetrated best of the true foster slugs tested. They penetrated to the center of the second phone book. |

Slug 1: 106.4gr (97.6%) Slug 2: 91.7gr (96.7%) Notes: These slugs expanded very nice. Unlike the Remington sluggers that produce the small slug the detaches in the center the Federal slug due to a reasonable large hollow point turn into rings and produce large internal holes in the phone book with good penetration. |

3.0 inches shells modified down to 2.5 inch shell*  5 shot group at 25 yards (click to enlarge) |
Chrono Testing 5 shots Low Velocity:1985fps Hight Velocity:2103fps Average velocity: 2043fps Extreme Spreed:118.0 Std. Deviation:55.33 Manufacture Spec: 1755fps Measure Mass: 114.9gr Manufacture Spec (114gr) Calculated Muzzle Energy: 1065ft-lbs Notes: Tremendous amount of Kinetic energy compared to the other slugs tested. The inconsistency in velocity is likely due to the after market role crimps I do after modifying them to work in the Winchester 9410. |

Impact with wet phone books Penetration: ~6.0+ inches The energy and hardness of these slugs gave them the best penetration. Only one was recover almost through the third phone book. The other slug exited the third phone book and was lost, like due to weakening of the phone book due to a near by hit. |

Slug 1: 106.4gr (97.6%) Notes: The slug recoverd did not expand hardly at all. Unlike the other foster slugs the Brenneke slug with its attached gas seal appears to be made of a much harder alloy. The combination of the highest Kinetic energy, heavies slug and hard alloy gave this slug the best penetration of the slugs tested. |
