Re: Vertical Dispersion
Sorry, poor choice of words on my part. I did mean to say that I was very careful to make sure each weighed exactly the same as the one before. But at this point, I'm not sure that helps. A week or so back, I wanted to test the consistency of my electronic. So I broke out the old Lee beam scale. Loaded five rounds off of it, five rounds off of the RCBS, then just for the heck of it, I dumped five more. Both weighed charges gave me 8" groups at 800 yards. The dumped load gave me a 6" group. I thought it was a fluke, and tried it again a couple of hours later. The wind picked up, one group was just over 10", the next just under 10" and the dumped load shot 8".
How tight should the bags be? I use the Sinclair adjustable front rest, and keep it snug to the sides of the stock. My left hand squeezes the Protector rear bag. It never touches the rifle. I've tried the ladder method with different powders, if this rifle has a sweet spot, it's hard to determine. It shoots good, but not good enough to make me competitive.
What would you consider the best distance to test loads?
If I can kill that coyote from here, Will you walk out to get him?
