This past Tuesday I was again testing/verifying several lots of Eley Match ammo I currently have. This testing is being done a 200 yards where Extreme Spread is king! My first group measured .387" for five shots at 200 yards with a 3 fps ES. The second group with the same lot was 1.5" with a 12 fps ES. Go figure? This is not, generally my best lot. My best lot shot .8" with a 6 fps ES. Two different lots that I have, each rated as 1062 fps on the box, shoot an average of 10 fps different. The good lot averages around 1097 fps and always has its ES at around 15 fps or lower. The "other lot" averages 1107 fps with around 20 fps ES most of the time. Occasionally it will spit out a decent ES. If I can put up the target you cans see the different lots with their velocity/ES together.  jpg hosting |

Can’t see your picture for some reason.
That’s some good shooting out of a 22 Richard especially at 200 yards. Good ES equals good groups? Is that what you’re seeing with your lot testing? Could you just test for ES using your lab radar to buy more of the same lot number?

I got it now Mark.
Yes, in my opinion,(we all have them) I believe that if you can test by ES, you will be able to get some good ammo. Am I going to say it's a slam dunk? No, but in all my testing of center fire, muzzle loading and rimfire, Invariably, that the shots with similar fps, will usually group together. Its one of the advantages of shooting with a chronograph of some type. With the LabRadar, I can just glance up after the point of impact and see the velocity. This of course only works well when there is little or no wind.
I watch some of these yahoo's on You Tube allegedly testing rimfire ammo with all degrees of wind blowing and no wind flags. They claim that "it is what it is?" To me, if you are not testing rimfire ammo under zero wind conditions or indoors, you are not getting valid results. I fully understand that at a outdoor match, you have to deal with the conditions that are present but.....you need to know the capability of your rifle and ammo under ideal conditions so when it comes to "holding off" (aka Kentucky windage), you know where your bullet is heading.
BTW, I shot again Tuesday, only a few groups at 200 yards as I was seeing some slight activity on the daisy wheels of my wind flags. It showed as my groups were off to the left by about 2" as compared to those groups in the picture. I did get a one inch group with Tenex which had a 3 fps ES. A second group with the same ammo had a 1.5" group with 12 fps ES and formed a diagonal.....some right to left plus a larger ES.
I had taken a chance when I bought those two bricks of Match rated 1062 (like my old lot of 1062). My hope was that it would give me similar results?..Wrong! It averages 1106 fps from my rifle where my "good-old" lot of 1062 averages 1096 fps. The ES on the new lot is in the high teen and low 20's where as the old lot averages 15 fps. I had bought four bricks of that old lot from the guy I bought the rifle from since it was not shooting in his new Annie. In the future, I will buy maybe one or two boxes of four or five different lots from Killough's (ones where they have sufficient stock.) I will head to the range when I get it and test at 100 yards under early morning windless conditions and decide if any are worth getting more. I don't shoot as much as you do so it might only be four or five bricks.
