I haven't done this at the range yet, and I'm not an experienced Garand guy, but when I was running some practice drills at home, I found that I loaded faster from my left (weak side) than from the right. Of course I'm probably conditioned by he other guns that I've done this with, but usually I like to keep my trigger hand in place on the gun, and execute the reload with the off hand. Are you saying that you find it faster to reload with the strong hand and then regrip to shoot?
