    Customer Accuracy Expectations

    This matches my experience as well. Good ammo is good ammo in good rifles. When shooters see different results with the same ammo in two or more good rifles, it's because no two boxes of the same lot of ammo are identical. While some lots may be more consistent box-to-box, the majority of...

    Customer Accuracy Expectations

    Ten shot groups as a standard. Wind plays a role at 50, a huge role at 100 and more huge beyond. (At 100 a mere 1 mph cross wind will move a bullet about .35".) At 50 a custom rifle should do sub-.300 (ctc) with good ammo and conditions accounted for. At 100 a custom should do sub-.900 with...

    DeLane Development Group Rimfire Ventures

    If enough groups with the same lot are compared, some may be somewhat smaller than others -- perhaps a very few significantly smaller. Not all lots of match ammo will shoot so uniformly that all groups will be nearly identical.

    For readers in general, Anschutz produces rifles with Fortner actions. Volquartsen doesn't.

    Accuracy testing methods… Paper Don’t Lie

    Everything with .22LR has a "best up to" distance. For some rifles/ammos it's not very far beyond the muzzle. For others it varies. As distance increases, the less reliable and repeatable the results can be. Random acts of accuracy can occur at any distance.

    300 yard consistency

    Multiple large scale tests prove .22LR tuners don't work? Litz's .22LR tuner testing was reported in his book Modern Advancements in Long Range Shooting, Vol. III. The .22LR testing was seriously flawed. It was based on unreliable ammo, SK Long Range Match, an entry level target ammo. All...

    Weird Eley Match Lot#

    Eighteen boxes of 50 rounds is 900. If I've misunderstood what you meant I apologize.

    Weird Eley Match Lot#

    The first post indicates eighteen boxes were tested, with half of them having the 20 fps difference. If all were shot within two hours, that would be 900 rounds within 120 minutes. A brisk pace, perhaps, but it wouldn't account for a distinct MV difference between half the boxes shot, which...

    Weird Eley Match Lot#

    Six bricks of one lot of Eley Match were ordered. All bricks/boxes have the same lot number. Eighteen boxes of this ammo have been tested, and half of the boxes have an average MV of 1091 fps with SDs in the 4 - 5 range. The other nine boxes have an average MV of 1111 fps (20 fps higher)...

    22 Rifle lands / compare discussion, significant differences

    There is no difference whatsoever in cartridge design, dimensions, or appearance between Center X and Midas +. None. They have the same ingredients/components and are put together during the course of the same production runs by the same loading machines. Only Lapua can fully explain why some...

    New .22 actions still coming?

    RTH1800 makes a very good point about older rifles. It's not necessary to have the newest or most popular model to get good results. While new rifles may have more appeal for many, there are older rifles that shoot very well. Of course with any rifle, newer or older, it's always about the...

    Bergara B14R Heavy Ammo

    Does it matter if rounds are over the speed of sound? The problem of transonic turbulence, which may affect the accuracy performance of some ammo, occurs when supersonic rounds slow down into the transonic range of velocities. The transonic range is between about 890 fps and 1340 fps. The...

    Any 22LR that compare with Vudoo?

    Since the post quoted (#18) is now over six years old, the question seems moot and quite belated. If they had their druthers many shooters would prefer to get the right thing first. ;)

    Need starting BCs. SK RM, Wolf MT

    As a general aside to the question, knowing the BC value of different rounds is only part of the picture. Those interested in trying to calculate or predict trajectory and POI based on MV and BC should be aware that, wind aside, there is at least one other important factor that will influence...

    More visuals are shown below. These have been posted elsewhere in the past. Eley is either on left or top.

    SK S+ deviation / Rimfire

    Ammo branded specially for "Pistol" is a niche ammo, even though anyone can shoot it. As a niche ammo, it's priced accordingly. Pistol ammo has no requirement to be a higher grade or to be better performing than "rifle" ammos. SK Pistol Match is graded below SK Standard Plus.

    SK S+ deviation / Rimfire

    According to a Capstone official, SK ammo is graded in the following hierarchy. For SK varieties nominally rated 1073 fps it's SK Rifle Match, SK Standard Plus, SK Pistol Match, and SK Magazine. For SK varieties nominally rated 1106 fps, it's SK Long Range Match, SK Biathlon Sport, and SK...

    SK S+ deviation / Rimfire

    The chronograph shows an ES of 93 fps for 65 rounds of SK Standard Plus, with an SD of 25 and a spread of 913 - 1006. The temps were about minus 15 degrees Fahrenheit ("+\- 15 F"). The cold temperature explains the slow MV of the rounds (it doesn't take long for a warm round to cool). The...

    deviation in cold .....5 degrees

    Comparing small sample sizes often gives unreliable data. When it's colder, all rounds will be slower. When it's warmer all rounds will be faster. With large samples, the standard deviation and extreme spread should be similar in both.

    Round count to determine the best lot# ?

    A lot of .22LR match ammo usually is about four to six cases in size, sometimes a little less or more. That's 20,000 to 30,000 rounds. In a .22LR match ammo population measured in tens of thousands, how many should be looked at before making an evaluation? What level of confidence is...
