Saw
gander's post on "Talk About Cheap" and thought, I'm not cheap - I'm anal.
I've gotten to the point where I plan my shooting session ahead of time and prepare my
loads and
targets in advance. I usually prepare five weighed charges for each load I want to shoot and put them in a baggie with the bullets. I use a different target for each five-shot load and label the targets in advance.
Here's a picture of my set-up for the next range session (anal enough for you?).
