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 obtruding 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 obtruding 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, lead 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.

I found a great combination my rifle likes: Strikerfire LDR (30" barrel), VORTEX Diamondback 4-12 scope, 115gr Blackhorn 209 powder, 350gr B.O.R. bullets. I am shooting 1" - 1 1/4" 3-shot groups at 100yds (off bench rest) with this combination. I shoot two rounds, then swab the barrel and shoot the third round. My barrel is measured at .502" diameter, and I can usually shoot 3-5 rounds before it gets hard to load the bullets (then I need a short starter to load it). I live and hunt in Arizona, so I have no restriction on using lead bullets. Try these out.

Great loading bullets

Have not had a chance to hunt with these but they load and shoot fantastic. Do not have force down barrel after shots and no need cleaning in between Shots.

good for CVA accura V2, CO

performed well after abandoning Powerbelts due to bad performance on elk in the field. easy to load, shoots well from my cva accura v2, with Bhorn 209 powder. shot a deer that was quartering towards me, coming down a small hill, at 40 yards. entered through neck, through vitals and lodged inside skin at opposite flank area. well-mushroomed bullet. can't wait to try on an elk.

Moose bullet

My wife and I each tool big bull moose in back to back years with the 350 bullet , one shot each. Highly impressed with them and they grouped well with blackhorn powder in my Omega.

Excellent Colorado round

Excellent round on the bench and in the field. Dropped a dandy 6x6 bull in his tracks this past September in Colorado. Would definitely recommend and will is on WI whitetail this December!
