    Sk standard Plus

    For what it's worth, SK publishes a G1 BC value of 0.172 for all it's standard .22LR bullets. But that number won't tell you where they will end up.

    New ELEY Ultra Extreme Long Range Round incoming

    With any .22LR match-type ammo, trust large samples of target results. Never trust small samples of target results. Chrony data doesn't determine what the ammo does on target.

    Summer Ammo Velocity

    One reason many longer distance .22LR shooters may prefer slower rather than faster average MVs is because a slower .22LR round will drift less in the wind than a faster one. Another reason is based on the mistaken assumption that .22LR bullets that exceed the speed of sound will suffer from...

    DESTABILIZATION

    There isn't a specific distance valid for all rimfire projectiles at which stabilization is lost. The same can be said for .22LR projectiles. There are too many variables. A google search that anyone can repeat shows that gyroscopic stability can be calculated using the formula below...

    Rimfire barrel cleaning

    The author Gregory J. Roman, claims using this cleaning method itself not only produced great groups on paper, it "also produces extremely low ES and SD numbers over the chronograph". What's not to like about that? The cleaning regimen itself improves chrony performance of the ammo. In other...

    1/2 inch at 100 all day long?

    Thanks. None of the match ammo I've shot at 100 yards has the consistency to produce more than the occasional exceptional or extraordinary ten-shot group at 100, if that can be taken to mean under .500" center-to-center. Of the few sub - .500" ten-shot groups I've seen, all were lone groups on...

    1/2 inch at 100 all day long?

    They are possible but not frequent or common. Certainly not consecutive, let alone all day long. I've shot many hundreds of ten-shot groups at 100 yards since 2021 when I first began. Few have been under half-an-inch. But there have been at least a couple. Below are the results with one...

    1/2 inch at 100 all day long?

    Half-inch ten-shot groups with .22LR at 100 yards all day long is a fantasy. It's such a tall order that it's impossible. Getting one or two half-inch ten-shot groups at a 100 out of ten groups is a good day. It's quite a challenge to shoot ten consecutive ten-shot groups that are all under...

    Lapua Ammo Lot numbers, most important numbers to match up

    How are they different now? The two lower boxes are made in 2021 and loaded by machines numbered 6 and 7. The top box is from 2023 and was loaded by machine number 5. (Lapua uses more than a single loading machine.)

    Lapua Ammo Lot numbers, most important numbers to match up

    When it comes to accuracy performance, it doesn't matter whether some or many shooters continue to believe that MV determines whether a lot shoots or not. Match rimfire ammo performance remains unrelated to what's printed on the packaging. Shooters should be aware and understand that no one...

    Lapua Ammo Lot numbers, most important numbers to match up

    Velocity means nothing here. Two or more different Eley lots that both have the same MV printed on the packaging can have different MVs when tested in your rifle. In other words, the same published MVs can have different actual MVs. The performance of each lot can be similar to each other or...

    Lapua Ammo Lot numbers, most important numbers to match up

    Matching the first five numbers will only ensure the manufacturer's rated average MV, the type of bullet, and the year of manufacture. The numbers following the slash in the lot number is what identifies the lot. The "speed" of the ammo is not relevant to its performance. Characteristics...

    Lapua Center X trending higher over time?

    Two things worth keeping in mind. One is that different boxes of ammo from the same lot can easily have different average muzzle velocities. The other is that temperature affects MV averages. As temps go up, so too do MV averages.

    200 yards with rimfire

    Is it possible that other lots of the same ammo would perform differently?

    Lapua Ammo Lot numbers, most important numbers to match up

    If you had a lot that shot especially well, the only way to find another like it is to test different lots to see how they shoot. Of course it's hard to know whether the lot is especially good or not until there are other results against which comparisons can be made. It may be reasonable...

    22 LR Mach Trimming

    Shooters, especially those coming from centerfire, have always desired improved .22LR ammunition. Too often the nature of related discussions convey the impression that .22LR development has remained mired in the past and its performance largely unchanged and unimproved. This isn't the case...

    Chronograph comparison, Garmin, LabRadar, Shooting Chrony

    Not all chronographs -- certainly the more affordable optical ones -- are equal. Perhaps this includes some such as this particular Garmin, despite its use of doppler radar. It's not as though the Garmin is a "high priced" device.

    22 LR Mach Trimming

    With Longshot's point that the smaller groups are smaller MOA-wise only, it's important to note that when convergence does occur, it's a random consequence, one that's relatively unusual, and unexpected. In other words, they are an unpredictable outcome that can't be produced on demand...

    22 LR Mach Trimming

    Litz says that at just above the speed of sound, the drag on a .22LR bullet increases enough to cause it to slow down faster than than a round that is below the speed of sound. The result of this is that ES of sample of shots fired downrange will be less beginning at about 30 yards or so than...

    New ELEY Ultra Extreme Long Range Round incoming

    Easier said than done. Reloading may be a good a solution when a reloader can load to similar standards as Eley and the other match ammo makers. Among current problems is that top quality pre-primed cases of are not available and crimping methods are often too inconsistent.
