    Question on Lapua performance differences

    X-Act, Midas +, and Center X are all Lapua standard .22LR rifle ammo, nominally factory-rated at the same MV of 1073 fps (of course, actual MV of lots will vary). Super Long Range and Long Range are nominally factory-rated at a faster MV of 1106 fps (actual lot MVs will vary). X-Act, Midas...

    DeLane Development Group Rimfire Ventures

    The author makes some specious claims that can mislead many readers who might take him seriously. He says that by following his cleaning regimen he gets great results downrange. He also claims that this cleaning method produces low ES and SD numbers. His words are below. Following these...

    The relationship between MV and POI with .22LR is not always consistent. While this isn't always clear at 50 yards, it is undeniable at twice the distance. That is to say, for a variety of potential reasons, by the point where distance is twice the usual BR distance, MV doesn't always predict...

    It can't be easy to compare reliably .22LR long range results between two or more rifles shot at different times. Even leaving potentially changing conditions aside, the longer the distance the more the many potential peculiarities of the ammo are seen, not just MV variation.

    School me on the Vudoo

    The assertion is that headspace variation, firing pin spring strength, and chamber length are more relevant to rifle performance than what a tuner can ever do. Does this refer to only the heavier barrels? Or does it refer to good barrels in general?

    What Anschutz is this?

    The serial number 53714 indicates the receiver is a 1966-proofed 14xx series single shot Anschutz match 54. The barrel is aftermarket as is the stock. It has a 1407-U9 trigger.

    Desert Precision Gunworks 22LR Action Updates

    In general when it comes to accuracy performance alone, .22LR shooters need not be concerned with keeping away from transonic/super velocities. If anyone shooting .22LR is concerned about transonic turbulence, it's not an issue with the vast majority of .22LR ammo. When transonic turbulence...

    Customer Accuracy Expectations

    There is a good explanation of group size analysis with regard to the number of shots in a group here http://the-long-family.com/group_size_analysis.htm Group size represents the repeatability of the rifle and ammo. Unlike good hand loaded CF ammo, no matter the name on the box with .22LR...

    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...

    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.
