Federal™ Muzzleloader Bullets are the most innovative muzzleloading projectile in decades that are redefining the accuracy and performance of modern, in-line muzzleloaders. The exclusive B.O.R. Lock MZ™ System provides outstanding accuracy in a non-sabot bullet design with sealing mechanism integral with the bullets, that is easy to load and approved for hunting in most areas. Fouling-cutting ring scours powder residue from the breech as the bullet is loaded, resulting in consistent bullet seating and reducing the need to clean between shots.

The system's foundation is a polymer cup that is permanently attached to the bullet base. Before ignition, the polymer cup remains positioned at the rear of the bullet, with the forward obturating ramp exposed, and only the fiber-reinforced base of the cup in contact with the barrel. At ignition, the polymer cup slides forward over both obturating ramps, creating the bullet's bearing surface, keeping the bullet seated and engaging the rifling. The resulting gas seal is incredibly efficient, and optimizes accuracy, velocity and consistency for shooter confidence.

The Federal™ Muzzleloader Bullets all-new technologies give hunters more reliability, consistency and accuracy than ever before. The heat-treated, copper-alloy bullet design features a polymer tip, with a deep, hollow cavity and skiving for consistent, devastating expansion. With no bulky sabot, required loading force averages about half that of most sabot bullets. In addition to extending the effective range of hunters and shooters, the Federal™ Muzzleloader Bullets feature a high ballistic coefficient for flatter trajectories and less wind drift to increase maximum effective range in the field, while delivering plenty of knockdown power with consistent expansion and weight reduction.

federal premium PMZ50TCI shot from a Knight Bighorn.

i have found for me the best set up is the PMZ50TCI bullet 100 grains of triple 7 fffg powder in a 50 cal knight Bighorn harvesting big deer in NE Iowa.

The Best In My Encore

They load and seal great in my TC Encore 50 cal but every gun is different
They Group great and are devastating on the Whitetails i have killed
Maybe they are not right in all barrels but my gun loves them
I used Barnes Ez Load in the past great bullet but i needed all i had to load the first one in a clean barrel with some bore butter on the sabots
Forget follow up shots , i had to pound the ramrod on a tree to seat the the 2nd bullet
Maybe my gun just has a tighter bore 🤷🏼‍♂️


Started using these, grouping was adequate , i took a buck this season and the entry and exit holes were superior to other bullets, great blood trail, buck was hot on a doe , he went about 20 yards , i wish i could get some more , everyone is out of stock

Great bullet.

Great bullet shot a elk at 200yrds little far back then a follow up shot at 25yrds.Both bullets did what they are supposed to do mushroom out and expand. I used 120 grains of triple 7. Did not have luck with the bh209 hangfires and misfires.
