Is this Ammo Worth Getting?

Let's returni to the point at the end of post #19.

There are some factors that the shooter can control, some that he can't. Shooters can control the shot execution. But they can't control the wind. Successful competitive BR shooters must be skilled at reading the wind by use of wind flags so they can shoot effectively whether it's windy or not.

I don't have such skills. My range is a small back corner range where the winds swirl and quickly change direction and strength. I've seen my meager three wind flags showing different winds at the same time. As a result, and especially at 100 yards, I try to shoot when there is no wind or at least as little of it as can be hoped for.

Could it be that wind helped make the May 24 results better than those from Tuesday (.960" v. 1.375")? How much wind was there?


Here's a short video of the wind conditions. It was taken between the first and second boxes of the second lot, the one shown above in post #17.

The closest "flag" (a rod with surveyor's tape) is at about 28 yards, the middle flag is at about 55 while the furthest flag is at about 75 yards.


It's obvious that there isn't a complete absence of wind. It's not unusual to have one or more flags flutter a wee bit on even very calm mornings. I suspect, however, that the wind isn't responsible for the 1.375" average.
 
One last post on this. Two things come to mind.

First, it's not fruitful to draw conclusions from a too small sample size. Ten ten-shot groups (100 rounds) doesn't seem to be enough. Even two sets of data that size don't seem to be able to provide enough information.

Second, there can be considerable variation between boxes within a lot of ammo. That is to say, two boxes of match ammo from the same lot can be sufficiently different from each other to give conflicting results.

If ammo from both lots shown was available in quantity, I wouldn't put either one at the top of my list. I'd be looking for ammo that gave a little more group size consistency. I'd be looking for ammo that had a lower ES than either of the two lots tested, ammo with an ES in the low 30's (or better, but that's very hard to find) -- and with an SD under 10.
 
Better shooter would produce better results with fine rifles. I have some holidays if you’d like me to come show you the finer points of consistent rimfire shooting. Don’t really understand how top quality target ammo from the same lot number can produce some very reasonable results and then such drastically different results out of the same rifle. Unless it’s completely shooter related
