Or shine a flashlight backwards through the scope to project the reticle on the wall. Line it up with a plumb line. Sent from my DROID4 using Tapatalk 2

I get what you're saying. But in defense of the original question (which wasn't mine, but is one I've heard a good bit), if there was a potential phenomenon that made your groups 2MOA at 100-300 yards, but 1MOA at 300 and beyond (exaggerated for clarity!), it would have significant implications...

Mind blown... that totally makes sense. Thanks for that bit of insight. My physics sense was never comfortable with the settling in thing, and this explanation fits well.

It's a demo... that's what it's supposed to do. They worked hard to build it, it makes sense to expect people to pay before they use it. Considering the niche aspect of their market segment, I think it's not unreasonable at all. Free demos work great for games and toys, but this is a...

If a match is 60 shots for record, I'll need a load that does well fouled, so it doesn't seem to make sense to develop for another condition. Sent from my ASUS Transformer Pad TF300T using Tapatalk 2

That's not a fair argument. Shooting paper at known distances may be the goal. For example, High Power and F-Class shooting is at paper at known distances. Consider also someone who may have access to a 100- or 200-yard range for frequent use, but must travel for matches at longer ranges...

Granted, "shoot steel to 1000" is not a comprehensive description of all Snipers Hide denizens. Long range marksmanship does not "equal" steel targets.

I corresponded with Chris Long recently, as a matter of fact. He argues that shots are normally distributed as random polar coordinates in a shot group. I have been collecting data to validate that assumption. So far, my testing indicates that groups are Rayleigh distributed -- normal...

Not at 300 yards, but here's how I keep track of my performance. I am trying to collect statistical data on a per-shot basis, so I create an amalgam target from the whole day's shooting. Here's a "30 shot group", which is an overlay of 10 3-shot groups. The 3-shot groups averaged 0.624 MOA...

Bank robber... sort of. I do information security: penetration testing, social engineering. In fact, I'm about to meet a client right now about masquerading as an auditor to gain unauthorized access to a bank. Sent from my DROID4 using Tapatalk 2

I believe Dan Newberry makes exactly the same point in his OCW materials. Namely, that deceptive anomalies can undermine the value of a ladder test, and lead the shooter to a false conclusion. I will be trying the OCW method for my next load. It is based on measuring the poa/poi metrics for...

I just did a seating depth test as well, and found that 0.040 was best. These are 190gr vlds in my 308. I thought that was weird, since I had expected closer to be better. Then I found a few articles from berger and others and discovered that 0.040 is a common sweet spot. I felt a little...

The problem with your joke is that those three questions have easier and more satisfying answers ;-). Sent from my ASUS Transformer Pad TF300T using Tapatalk 2

As far as I know, it's a crater if the edge of the firing pin impression rises above the surface of the rest of the primer. I can definitely feel the rim with my fingernail. I've looked at every picture I can find on the Internet of a cratered primer. I know that mine are very minimally...

Cool. Thanks for the help. I had run across the r700 idiosyncracy, but was not aware that Savages were known to do similarly. Thanks! Sent from my ASUS Transformer Pad TF300T using Tapatalk 2
