After 6 months of 45 acp reloading and beginning to transition into a couple more interesting calibers (223, 7x57, etc), I decided I needed a chronograph.
Took it out for the first time yesterday. I am addicted. I was actually impressed with the velocities I am getting out of my 5" 1911. My real question is-
What is an 'acceptable' standard deviation? I searched a bit, and didn't find much except for 'under 10 is good, over 30 is bad.' Can anyone offer any more insight than that? The std deviation for the 230 grain LRN load I have been running was 8.8 at about 850 fps.
p.s. I also found out what happens when you switch from a pistol to your iron signed AR, and don't change your point of aim. I shot my chrony the first time out. grrrr.
