    New ELEY Ultra Extreme Long Range Round incoming

    Perhaps the bullet used in this "new" ammo is a bullet already in use with other Eley varieties. While RWS Plus Long Range (and the rebranded Norma equivalent) have a new bullet design, Lapua Long Range and SLR use the same bullet as CX, M+, and X-Act. It outdoes RWS and Lapua in the naming...

    Lapua Ammo Lot numbers, most important numbers to match up

    As 1813Benny says, when looking for the same lot all the numbers must be the same. It's worth keeping in mind that the size (number of rounds) of .22LR match ammo lots often makes finding more of a particular lot impossible. Typically the higher the grade, the smaller the size of the lot...

    Expected Accuracy for Range/Practice Rimfire Ammo (outside at 50, 100, 200)

    Consistent results are not to be expected, especially as distance increases. Consistent results can be elusive with top tier grades of match ammo. Lesser grades of match-type .22LR ammo -- the entry level kinds -- generally don't produce consistent results. For example, a few ten shot groups...

    Effects of bore quality on ES and SD???

    Stev0, one barrel is always faster than the other, not mostly or sometimes. I regret the confusion as well as saying anything.

    Effects of bore quality on ES and SD???

    For the single use of the word "consistently" in the sentence, you would have always preferred to see it as "...one is consistent faster than the other"? If that's the case, now you have it. ;)

    Effects of bore quality on ES and SD???

    I have two rifles from the same manufacturer with barrels of the same length. With the same lots of ammo one is consistently faster than the other. The slower barrel is about 50 years older but shoots just as well as the newer.

    Can someone explain this?

    The SK PM results had nothing to do with it being a so-called pistol round. Pistol Match is made on the same production run as SK Rifle Match and SK Standard Plus using the same components including powder. What should be kept in mind is that SK ammos are entry level .22LR match ammos which...

    The whole box at 100 yards

    The first time I shot 50 at 100, the results were surprising. Below is the target, with two obvious outliers. The widest outside-to-outside measurement was 1.709" -- or about 1.5". (Edit: that's about 1.5" center-to-center.) I've tried 50 at 100 on a couple of other occasions without...

    Old Anschutz .22 Garden gun

    The Flobert I action was used on inexpensive Anschutz models. Part of the stamping visible in one of the pictures in the OP has "Cal. 22 long r". If the complete stamping is 22 long rifle, the firearm should be good for .22LR ammo. In this case it will have a rifled barrel, not a smoothbore...

    Old Anschutz .22 Garden gun

    The headbanner stamping on the top of the front of the receiver indicates manufacture between 1950 and 1955. By post-WWII agreement, German arms makers were not allowed to produce rifled barrels until 1953. As a result, if the barrel has rifling it suggests a date of manufacture of 1953 or...

    1/2 MOA at 100 yards, all day, every day!

    With the same varieties of .22LR match ammo up to 100 yards or so, minor variations in BC won't make any meaningful difference in accuracy performance. Especially at distances beyond 50 yards, MV variation will play a bigger and bigger role. So, too, will variation in Cg from round-to-round...

    22LR Barrel Length and Twist Rate for PRS and ELR

    This observation intentionally or not points to the role of what's favored or in vogue among shooters posting on rimfire forums. While there's a great deal of anecdotal reporting, there remains no published and verifiable data to show how much, if at all, fast twist improves performance. More...

    Do we care more about, SD or ES?

    It's very straightforward to collect SD and ES data. It's not easy to calculate .22LR BC values. In any case, the former will have an influence greater than BC. Precision is non-linear as distance to target increases not because of BC variation but because of MV variation and Cg variation...

    The effects of the transition from super to sub sonic on the 22lr

    This experience may not be unusual. There are ammo-related reasons for this, and different lots will be better or worse than others. What may have been unusual is if all the rounds continued to produce MOA groups at 100. Often this level of consistency -- regular MOA -- isn't seen throughout...

    Do we care more about, SD or ES?

    Lee, the link was included only to show four small ten shot groups. That's all it was meant to illustrate. It wasn't a recommendation for or against composite groups. Don't make an issue out of nothing. A chronograph isn't necessary to see how an ammo shoots.

    Do we care more about, SD or ES?

    The information in the link was included only as illustrative of results achieved with a good rifle/barrel and good ammo. It wasn't prescriptive or a recommendation. No one needs to prioritize composite groups over any other, whether it's 25 or 40 round or something else. Of course, a...

    Do we care more about, SD or ES?

    Since there's considerable misapprehension and misinformation about chronograph results, it may not be a surprise if remedying the lack of chronograph data is not a priority. What's ultimately important is the results on the electronic target regardless of what the chrony might show. With...

    Do we care more about, SD or ES?

    It's not so much the "potato" (?) bullet shape or its BC that prevents many shooters from seeing repeatable 0.0xx groups at the testing center or elsewhere. Two things must always be kept in mind. One is that not all rifles/barrels can shoot so well, regardless of ammo. The other is that not...

    Do we care more about, SD or ES?

    ES is not a reliable indicator of ammo quality. It can't guarantee results. It may not be helpful to predict results. After tracking MV vs POI for hundreds of ten-shot groups at 100 yards, it's clear that the relationship between the two is not consistent. The inconsistent relationship...

    Do we care more about, SD or ES?

    For those who use a ballistics calculator to help prepare for shots at long or varying distances, when using the same kinds of bullets that weigh the same nominal 40 grains there's not much else ammo-related to enter. Ballistics calculators predict what should happen when using bullets that are...
