[QUOTE="OldElkHunter1961, post: 2439279, member: 121205"] WRT "vents" drilled into an existing barrel the length of the drilled/vented portion of the barrel effectively decreases barrel length by that distance (22" barrel, drilled segment 1.5" = 20.5" new effective barrel length). How much velocity is lost depends on what percentage of total barrel was "removed." The shorter the barrel the greater percentage of barrel lost. WRT suppressor effects on velocity I've only seen anecdotal changes in bullet speed. Meaning low single to low double digit increases. Only my experiences, I'm not a ballistics laboratory. Just a curious shooter. Enjoy the tinkering. [/QUOTE]
