[QUOTE="Bart B, post: 1158159, member: 5302"] 22 rimfire bullets shoot slower from barrels longer than around 20 inches. I see no reason to think center fire barrels don't have a length limit before their bullet leave slower. They do for the first inch or two. High pressure gas ejecta pushes them just like blowing a balloon sideways with a puff of air from your lungs. That gas leaves at least two or three times the speed bullets do. Ones ability to fit good parts together to make an accurate rifle and ammo plus making wind corrections really well doesn't qualify him as an internal ballistics expert. Once the powder "envelope" is exhausted in a barrel, the pressure inside is at zero. There'll be no muzzle blast whatsoever. [/QUOTE]
