My split times are not real good. I shoot a P14-45 and am trying to develop better split times. Rather than burning thru a lot of ammo to do so should I use my Ruger 22 rather than my P14-45? I think I am pretty good about trigger reset, just a bit slow overall. Also, I was working on my split times today at about 8 yards. Should I start at 3 yards and then work my way out?
