Federal Premium Launching New, Revolutionary Muzzleloader Bullet Design

Federal Premium is striving to redefine modern in-line performance with its new Trophy Copper Muzzleloader bullet, which features one of the company's latest innovations: the B.O.R. Lock MZ system.

The 143rd NRA Annual Meetings & Exhibits are just days away, and the first new product we've heard about could prove to be revolutionary. Federal Premium Ammunition is striving to redefine modern in-line performance with its new Trophy Copper muzzleloader bullet, which features one of the company's latest innovations: the B.O.R. Lock MZ system.

Designed to provide top-notch accuracy in a non-sabot design that's easy to load, scrubs fouling from the breech and ensures consistent bullet seating, the B.O.R. Lock MZ system's foundation is a polymer cup that's permanently attached to the bullet base. Yes, you read that right—it stays attached. This isn't a sabot, but it's not a belted bullet, either. The force of ignition pushes the cup forward onto raised bands along the bullet shank, expanding its diameter. That engages the rifling and seals the bore, optimizing velocity and accuracy.

“B.O.R. stands for ‘Bullet Obturating Ramp.’ The walls of the polymer cup get pushed up and out, into the rifling,” said Bryan Peterson, Federal Premium’s Senior Product Development Engineer. “You get an excellent seal—and that means better ballistics and downrange performance.”

The design is meant to serve as Federal's effort to develop a completely new class of projectile.

“The time was right. We weren’t going to get into the muzzleloader market with the same sort of bullet designs that have been around for decades,” said Mike Holm, Ammunition Product Line Manager for Federal Premium. “Instead, we used our 90-plus years of ammunition manufacturing expertise to create something special—something that would let muzzleloaders hunt legally in more places, with better accuracy, dependability and ease. It’s a true 200-yard muzzleloader bullet.”

The rear of the B.O.R. Lock MZ cup features a hard, fiber-reinforced polymer ring that scours fouling from the breech as the bullet is pushed into place. The ring is designed to decrease the need to clean between shots, and should make it easy to seat each bullet in the exact same depth every time.

Like other projectiles in the Trophy Copper line, the copper-alloy bullet features a polymer tip, with a deep, hollow cavity and skiving that allows for consistent expansion.

Features Include:

• Will initially be available as 50 caliber, 270 grain bullet
• B.O.R. Lock MZ System: Expanding polymer base cup engages rifling and seals the bore for extraordinary velocity and accuracy
• Non-sabot design is approved for hunting in most areas
• Trophy Copper bullet features a polymer tip, with a deep, hollow cavity and skiving that ensures consistent expansion
• High ballistic coefficient flattens trajectories and minimizes wind drift
• Required loading force averages about half that of most sabots
• Fouling-cutting ring scours powder residue from the breech as the bullet is loaded, resulting in consistent seating and reducing the need to clean between shots

15-pack units of the new projectile are expected to ship with an MSRP of $24.95.

this is a very accurate easy loading bullet. 2 inch group at 100 yards. cleans the rifling as you reload so you can shoot more between cleaning. definitely leaves a nice hole in deer. its still in the testing phase, so its not yet available to the public. i got mine from a guy that works at federal and he gave them to a few guys to test. overall i like them way better than the sabots and powerbelts. nice crisp crack when shot, almost sounds like a rifle. definitely a good seal.

This is nothing other than a Barnes bullet w/ a sabot attached. The other thing is that the price is too much. Sell the 15 pack for 15.00 and sell them all day.

I've looked at every outdoor location I know and no one has these bullets yet. Where and when can I get them? Thank you! Ron

I am hoping that they are easy enough to load that you won't have to pound them down hard w/ramrod. Are they out for sale yet? I couldn't find them online for purchase.

It might be too long to stabilize in 1-28' twist? Also, what about magnum 150 grain loads or 120 grain BH209?

I thought I heard Colorado did away with that reg on bullet legnth.Maybe I'm wrong.

I believe the 2x rule in Colorado has been relaxed. we might want to check out the regulations and see what's up with that. I'm going to give these a try in my TC PH!

What with the morons in Californa having just passed legislation banning lead bullets, this is good news... still, it would be nice if they remembered the .54 cal folks - hopefully, that's coming.

I think that the use of the term 'breech' is misleading, since most people regard that term as applying to the face of the plug. The scraper base pushes fouling down the barrel to the top of the powder charge to reduce buildup in the barrel. Sounds like it will work very well--unless, of course, you own a .45, .54, or .58 caliber-in which case you are out of luck.

Savage clearly states to use smokeless powder with saboted 45 cal bullets ONLY. Having a cup around the bullet expand to fit the rifling appears to be a good idea, however I have concern how this would affect the pressures found in a rifle designed for smokeless powder .

How about .45 cal. for the smoke-less muzzle loaders

I would like to know what Federal has listed as the BC on this round.

What's the factory BC listed on this bullet ?

It seems to me that the fouling-cutting ring would add more residue to the breech each time you load your rifle. Am I missing something?

I wish these companies would get off the .50 caliber bandwagon in BPS muzzleloading. Most use them for deer hunting and a 270 gr bullet is so much overkill, it's ridiculous. I've used a .45 cal for years and IT'S overkill!

How far does it travel before engaging the rifling and what holds it tight against the powder?

15 bullets for $25.00 that is a little high for me I'll stick with my home made rounds they work and don't cost over 25¢ a round.

@sandyj I don't see why there would be any problems since most ramrods are concave to allow for a pointed projectile to be loaded without issue. I can't see it loading any differently than other polymer tipped projectiles. Will be looking forward to trying these.

Will it work with the Savage 10ml smokeless powder loads?

April 23, 2014

my only question is: how does the bullet respond to a ram rod. since it is in a pointed head instead of a flat head load . is there any damage to the head of this new bullet ? on loading it from the front .

Wouldn't mind trying that in my 50cal BoneCollector on some Colorado Big Game.

Colorado allows conical that are less than 2x diameter. This bullet may be too long.
