As to the argument that goes, it's always been done" all fine a good, but I've looked at a lot of old BP cartridge chambers and guess what, many or most, if they've been fired a lot in their history, have a small ring in the chamber neck right at the point where the bullet base would be seated in the loaded round. 7] to force the case head back.

To illustrate the effects of variations in bullet travel before the bullet enters the rifling, we'll compare a standard load with adjustments made only in the bullet's seating depth. Over time the first couple of inches in a barrel that are just forward of the chamber will wear in a couple of ways: Cracks and pits will develop, and the lands/rifling will erode. By the time I got to the range, about 40 miles away, some over dirt roads, the powder had settled. Put me on your customer list. Generally, for a BPC I compress the powder anyway. Another way to think of it would be: if there were no potential for a problem then why not just put a card wad on top of the powder (regardless of powder type) and leave an airspace between the powder/wad and base of bullet?

In a gun barrel, smokeless powder burns, creating gas. Hunting success relies more heavily on skills and proximity to the game. 7] to force the case head back. With commercial hard-cast bullets, low pressure loads will cause leading at the chamber end of the barrel, so I wouldn't mess with lower velocity loads unless you're getting leading at the other end.

The punch is a rod shaped and fitted to the die cavity. What happens is that when there is too much fluidization going on in the fluidizing hopper and you get lots of air bubbles. A bullet that is fitted properly and centered in the bore as best as can possibly be done prior to obturation will have the best possibility of fine accuracy because it is most likely to remain balanced. Black powder loads (and black powder substitute loads) are another matter entirely. This means that the flow coming out of the gun is not a consistent mix of air and powder; there is too much air. A few exceptions, most high-velocity.22 center fires have either a 112 '' or 114 ''.
