Black Powder Muzzleloading Rifle / Rifle And Rifling Definition.
 Rifle is defined as; A shoulder fired firearm of which there are spiral grooves cut into the bore or rifling.
 Rifling is defined as; Spiral grooves cut into a gun barrels bore for the purpose of spinning a projectile as it travels down the bore which stabilizes the projectiles flight once exiting the bore. Spiral grooves in a gun barrel bore.

Black Powder Muzzleloading Rifle / Barrel Twist Rates.
 The rate of twist in a muzzleloader barrel determines the optimum projectile length and speed of the projectile by applying the proper spin on the projectile to prevent it from yawing and pitching. Expressed in terms of the number of revolutions per inch of barrel length, this ratio is commonly expressed by designations such as 1:28, 1/28 or 1 in 28 twist, the 1 represents 1 twist, the 28 represents inches of barrel length.

 How do you know what is right? A good rule of thumb is that the heavier and longer a projectile is, the faster the twist rate needs to be and therefore a lighter shorter projectile needs a slower twist rate to give proper spin for correct flight.

 Usually rifle barrels with a;
1 turn in 66" rifling will do best with round ball,
1 turn in 48" round ball, ball-ets, short conical bullet and saboted pistol bullet,
1 turn in 28" conical bullet and saboted bullet.

 Always keep in mind that by adjusting powder charges up or down you will find a charge that most likely will work for the projectile you are shooting because speed and rifling twist work in conjunction for projectile stabilization.

Black Powder Muzzleloading Rifle / Caliber Selection.
 When selecting a black powder muzzleloading rifle you first need to establish what it will be used for, below is a brief general caliber suggested use listing which is based on muzzleloader bullet or projectile wound channel and energy for hunting purposes.

(.36 cal. dia.) Thirty six caliber and smaller bore diameter black powder muzzleloaders are a good choice for small game like rabbits and squirrels.
(.45 cal. dia.) Forty five caliber bore diameter black powder muzzleloaders are a good choice for deer, small game and varminting.
(.50 cal. dia.) Fifty caliber bore diameter black powder muzzleloaders are a good choice for medium to large game such as antelope, whitetail deer, mule deer and elk.
(.54 cal. dia.) Fifty four caliber and larger bore diameter black powder muzzleloaders are a good choice for big game like mule deer, elk, moose and bear.

  All rifled muzzleloaders (rifles), at least 45 caliber, ammunition restricted to minimum diameter bullet no less than .440", ignition system restrictions for this class none, sight restrictions for this class none, effective range 200 + yards.

Black Powder Muzzleloading Rifle / Power.
 While many people wonder just how powerful a muzzle loading rifle can be without the use of smokeless powder, others have been building, the ultimate muzzleloader.
 Once you are allowed to use modern centerfire primers for powder ignition, there is very little to no difference in performance between muzzleloaders and modern centerfire high power rifles.

 Ultimate Firearms, Inc. offers their powerful BP Xpress muzzleloading rifle that can be fired and burn 250 grains of pyrodex pellets. The rifle will fire a 300 grain bullet at over 2500 feet per second and a 180 grain bullet at 3100 feet per second. The Ultimate Muzzleloader has been subjected to just over 125,000 psi breech pressures. The rifle has a lugged, locking bolt with two blow by ports to prevent any primer blowback. Due to the patented ignition system, there are no gases expelled through the breech plug.
