Some FAQs from their site






What caliber is the Bad Bull Muzzleloader?
The Bad Bull Muzzleloader is a 45 caliber. We chose the 45 caliber over the 50 caliber because we can obtain a higher velocity and a flatter trajectory. The Bad Bull Muzzleloader delivers over 6000 FPE of energy at the muzzle and retains 2500 FPE at 300 yards using our 275gr bullet. Another plus for the 45 caliber is that it has less recoil than a 50 caliber.
What bullet do you recommend?
We recommend the 275gr Parker/Bad Bull Ballistic Extreme. With this bullet, we are obtaining velocities of 3100 FPS from the X Series Bad Bull. Trajectory is very flat. Set 3" high at 100 yards, the bullet is still 3" high at 200 yards. It comes back to zero at 265 yards and is only 3" low at 300 yards. Also, accuracy has been very good. We have customers reporting 1.5" groups at 300 yards.
What type of Powder does the Bad Bull Muzzleloader use?
Our muzzleloader is designed to use modern smokeless powder. This eliminates the messy clean up associated with black powder. Black powder is also very corrosive and can damage muzzleloaders very quickly. Also, it is well proven that smokeless powder is ballistically superior to black powder. NOTE: NEVER use smokeless powder in any other muzzleloader. It could result in injury or death. The Bad Bull Muzzleloaders are designed for the higher pressure generated by smokeless powder.
What load is used in the Bad Bull?
The Bad Bull Muzzleloader uses IMR 4350 smokeless powder. The minimum load is 100gr. DO NOT drop below 100gr, or DO NOT exceed 140gr of IMR 4350. We recommend a 45 Wonder Wad on top of the powder charge with our 275gr bullet seated on the wad. A Large Rifle Magnum primer is used to ignite the charge. We use a Federal 215M Primer. This is the only Primer that performs properly in the Bad Bull Muzzleloader.
Can I experiment and use other smokeless powder?
Definitely NOT! Use only the recommended charge of IMR 4350 Powder. The muzzleloaders have been pressure tested using the powder charge. If you experiment with other powders, you run the risk of damaging or destroying the muzzleloader, in addition to the risk of injury or death. Use only the powder and charge recommended by Bad Bull Muzzleloaders.
Can I use pellets (black powder substitutes) in this muzzleloader?
Yes, black powder substitute pellets may be used. You may use 3 or 4 black powder pellets (50gr each) in the Bad Bull Muzzleloader. CAUTION: Do not exceed 4 pellets. That is the maximum load. Do not load 4 pellets in any other muzzleloader. The Bad Bull Muzzleloader is designed to withstand this pressure: others are not. Clean the muzzleloader as soon as possible after use.
Can I use black powder in the Bad Bull Muzzleloader?
No. The flash hole is not designed for the use of black powder or black powder granular substitutes.
