Description
Honestly, I don't get the practice of sizing pellets. To me, all sizing does is "pre-squeeze" the pellets down to a smaller size - and the barrel will do it for you anyways! I do have a pellet sizer, and I only use it with the largest dies to uniformly size the skirts (it does not even touch the heads). This lets me do roll testing, and I used to do a lot of that before the PelletGage came out; now I rarely do it. The basic idea behind a wxBoxSizer is that windows will most often be laid out in rather simple basic geometry, typically in a row or a column or several hierarchies of either. All sizers are containers, that is, they are used to lay out one dialog item (or several dialog items), which they contain. Such items are sometimes referred to as the children of the sizer. Independent of how the individual sizers lay out their children, all children have certain features in common: wxGridBagSizer is a rather special kind of sizer which, unlike the other classes, allows to directly put the elements at the given position in the sizer. Please see its documentation for more details.
All I can say is, try it and see.... If you get the perfect combination of sizing, head and skirt, for your gun and pellets.... then the consistency that allows can't be worse.... and should eliminate those annoying "flyers".... The only plus side I can see to it is that loading should feel more consistent, but to me that is vastly offset by the fact that skirt is likely to be of a smaller diameter than the barrel as the pellet sits after loading, due to the chamfer of the leade in. That lets the pellet sit off square (and perhaps more importantly, in a variable position) as it gets hit by the air upon firing, and that just can't be good.One other thing - the sizing listed on most tins, including H&N and JSB, are pretty much meaningless. I sample each new lot with my pellet gauge and note the data on the tins as I get them. The ones I know will shoot poorly get set aside for tuning and testing, or sometime offhand if I have not been shooting that way for a while (a little more variation there is hard to notice ). Even though, HAZEMAG Center Sizers are available for primary or secondary applications, we do not show this in different models or types. The difference is made by the type of used rolls, with or without breaker bar. However, as a rule of thumb it could be said that a primary center sizer starts at a diameter of 1,000 mm, whereas secondary center sizers end at that diameter. I don't agree with Alan."the fact that skirt is likely to be of a smaller diameter than the barrel as the pellet sits after loading, due to the chamfer of the leade in" makes no sense. The pellet skirt is flared precisely for this reason, to be wider than the barrel and to seal into the chamfer to allow air pressure to expand it to groove depth."and the skirt is always far larger than the head" seems to be in direct contradiction to the above statement but does seem to be desired. The skirt starts out larger than the head to center the pellet and allow the skirt to seal to the groove diameter when fired. Pretty much everything reasonable is worth trying, so test it out. I, like Bob, no longer do much sorting - although I sometimes do some in the crappy winter months if I have the time. Sorting for head size gives me the better results than out of the tin, and then weight sorting on top of that is the gold standard in my book - if the shape is the same (from a head size standpoint) and the weight is the same, then we will get the lowest variation in BC that we can expect. I still maintain that this (BC variability) is the key - so many get their ES down to under 1% at the muzzle, but if you test it at the target you will see a much higher number, and BC has to be the majority of that. As BC varies, flight time and wind drift vary even in identical conditions.
On the right, there’s a chart with the 3 most common ring size systems used in UK, USA and internationally. For Australian sizes simply refer to the UK sizes, which are the same. WHY USE A RING SIZER?

What makes sizers so well fitted for use in wxWidgets is the fact that every control reports its own minimal size and the algorithm can handle differences in font sizes or different window (dialog item) sizes on different platforms without problems. For example, if the standard font as well as the overall design of Linux/GTK widgets requires more space than on Windows, the initial dialog size will automatically be bigger on Linux/GTK than on Windows. These are JSB Exacts, the two on the left were fired, the two on the right just pushed through the bore.... The exact shape of the skirt after firing depends on many factors, including the pressure, bore fit, pellet alloy, presence of a choke or not, etc.etc…. That is one reason why the BC of any pellet can vary from gun to gun....
The next section describes and shows what can be done with sizers. The following sections briefly describe how to program with individual sizer classes. wxFlexGridSizer is a sizer which lays out its children in a two-dimensional table with all table fields in one row having the same height and all fields in one column having the same width, but all rows or all columns are not necessarily the same height or width as in the wxGridSizer. So far I've found that finding the right pellet/bullet/power settings for your particular PCP puts those magic "bugholer groups" in hand...BUT...doing the myriad tests for the 10 shot, one hole benchrest group is still very satisfying and reading about them fills those wintry snowbound hours. Bob and Alan, did you read all of my post? The Robb sizer is apparently designed for exactly what is being discussed. Are you two not understanding this concept or are you stating that it could not work?I understand perfectly.... If you use a tapered sizer, and the taper is such that it ends up sizing both the head and the skirt to the perfect diameters for your gun, you may see better results.... Of course if the length between the head and skirt is different, for different pellets, the taper inside the sizer would have to be different to do that, right?.... (slower taper on long pellets, faster taper for short ones)…. It is very important to find out the correct ring size whether the ring is for you or another person. This measurement enables us to provide you with a perfectly fitting ring. A ring that is so small you cannot get it on – or so big it falls off – can really ruin a big moment! 1) OUR RING SIZER APP wxStaticBoxSizer is a sizer derived from wxBoxSizer but adds a static box around the sizer. Note that this static box has to be created separately. There are currently five different kinds of sizers available in wxWidgets. Each represents either a certain way to lay out dialog items in a dialog or it fulfills a special task such as wrapping a static box around a dialog item (or another sizer). These sizers will be discussed one by one in the text below. For more detailed information on how to use sizers programmatically, please refer to the section Programming with wxBoxSizer. I would rather be shooting than get all worked up over a few thou difference in group size that in all probability is not repeatable anyway.
