[QUOTE="edge, post: 1128801, member: 5030"] The only question is the rifled barrel length needed for accuracy. Let me make it more clear, a Railgun Pistol for shooting a subsonic bullet. Perhaps for simplicity a .45 with say a 200 grain bullet @ 1000 fps. All I want to know is whether the barrel length has anything to do with accuracy or is the only reason for a long barrel velocity? IF the only reason is velocity ( along with low muzzle pressure/Blast ) then how long does it really need to be? Say a super quality barrel on a snub nose .38 mounted on a 50 pound platform firing at 1000 fps COMPARED TO A 30 inch barrel same caliber same velocity same platform would you detect a difference in accuracy?
