Sorry G I didn't make my self clear when I said speed I ment the
speed a follow up shot could be taken not the speed of the bullet
Magna porting is for control and is usualy only done on action
shooting guns in the major calibers
major caliber is any pistol giving the same or more energy than
a .45 ACP round

sorry for the confusion Aitch
