[QUOTE="itchytriggerfinger, post: 2099024, member: 24854"] I understand that. What I’m trying to figure out is if there is any data on what is the most efficient length of tube for a given cartridge/barrel length. At point point does pressure peak and start declining causing diminishing returns on barrel length? What would it benefit me to carry a rifle with 26” of barrel if I could get the same velocity out of 20”or 22”? I knew when I cut off 4” of my 308 that I was gonna give up velocity but since I was dedicating that rifle to subsonic use that losing 4” would be irrelevant. I also know that were I to add 4” to barrel length it would not necessarily mean that I would see an increase in velocity once powder was consumed and pressure was on the downward, so where is that point? Can it be calculated? [/QUOTE]
