    Handicapping Myself With 7X Scope?

    The handicap is the inconsistency of the ammo itself. Unlike .22LR, there is no .17HMR match ammo. With good match ammo, sub-MOA results will be more common with .22LR than with .17HMR -- even if shooting 5 round groups with .22LR, while the 17HMR shoots 3 rounders.

    Eley or Lapua?

    Landy, Thanks for the explanation. It confirms what I believed but did not know for a fact. I don't think much about BC as it doesn't change what I do with the ammo I use at the distances I shoot.

    Eley or Lapua?

    I just saw your question as I was posting. I don't know the answer as it's above my pay grade. Someone who may know is Landy (poster HuskerP7M8). His posts over the years have informed and illuminated the issue of center of balance problem of .22LR ammo.

    Eley or Lapua?

    What distance? The very same distance the vast majority of Lapua Midas + and X-Act are used -- 50 yards. Both .22LR BR shooters and 3P shooters shoot 50 yards or meters and they use more of these ammos than shooters in other disciplines. It's hardly the case that ammo manufacturers don't...

    Eley or Lapua?

    Can an ammo be "optimized" for a certain distance? If the relatively close distances where every ammo will perform well are disregarded, will ammo that performs well at, say, 50 yards/meters continue to perform well as distance increases? Is there something that can affect the way a bullet...

    Eley or Lapua?

    Are there lots of Lapua that will shoot as well as the Eley? Of course there are such lots. The real question is: can they be found? This can only be answered by testing to find out first hand. Any shooter testing for long distance would be well advised to test at those distances. Why...

    Temperature sensitivity

    Neither standard rifle match ammo (e.g. Lapua, Eley, RWS) nor biathlon ammo have lube on the cases. Any lube used specifically in case manufacture is washed off. All, however, have lube on the bullets.

    Lapua Biathon Extreme

    It's not clear that Polar Xtreme remains in production. On the Lapua rimfire products webpage, Lapua notes the following: At current, Lapua offers the following .22lr rounds: X-Act, Midas+, Center-X, Polar Biathlon, Pistol OSP and Pistol King. See...

    Temperature sensitivity

    A study on External Barrel Temperature and Precision was published online in 2013 and may be of interest to some readers. See https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3944560/

    CCI SV Bullet Length in Kestrel

    It's little wonder that ballistics calculators are not always able to explain or predict the behavior of .22LR ammo, even match ammo. Unlike jacketed bullets, soft lead .22LR bullets are not exactly uniform. The best lots, which will perform well at all distances, will have bullets that are...

    Hotter ammo for “fast twist” barrels

    It's possible that a lot of viewers miss it because it intuitively sounds correct. Even the video maker thinks it is. The poorly informed claim is made in both versions of what's very much the same video. In the more recent version it's made arount the 12:30 minute mark. In the older one...

    Hotter ammo for “fast twist” barrels

    Perhaps their .22LR videos should be viewed with caution. In them it's claimed that faster MV's are much better because faster .22LR bullets are less affected by wind drift than slower ones.

    How good can you shoot CCI SV?

    This is fact. No rifle, whatever its make, can outshoot the ammo its given.

    Practicing for long range - options when you are capped at 200 yards??

    If someone regularly shoots .5" to .75" ten-shot groups at 100 yards with a Ruger American Rimfire using Federal Automatch, the word to describe it would be incredible.

    How good can you shoot CCI SV?

    Every inexpensive .22LR ammo can have random acts of accuracy. CCI SV is like that. Better ammos will shoot well more predictably.

    22 Rimfire barre choices/recommendations

    Perhaps the OP stopped wondering what experiences others had some time after posting his question two-and-a-half years ago.

    22LR ammo Question

    While ES has the appeal of being easy to understand, ES without SD gives only part of the picture. Since many chronographs will calculate the SD with no effort on the part of the user, it's worth knowing why SD offers a more complete picture of the ammo. ES shows only what are the fastest and...

    22LR ammo Question

    It can't be taken as a given that one shooter's chronograph data remains valid for other shooters. The data obtained over the chronograph from one variety of ammo, say CX, will vary from one lot to the next. It may also vary from one rifle to the next.

    22LR ammo Question

    One of the potetial problems with testing at places such the Lapua or Eley facilities is that too few rounds may be tested before a lot is selected. It's possible for some lots to produce results that aren't consistent, that aren't all similar to the best results obtained. Some groups may be...

    Is my barrel shot?

    A clean, unfouled barrel is always inconsistent. Fouling it is necessary. The source linked above alleges that a great deal of fouling is required for consistent performance. According to Roman, "Seasoning will start to build up in the breech end of the barrel and eventually build up all the...
