Sizers, as represented by the wxSizer class and its descendants in the wxWidgets class hierarchy, have become the method of choice to define the layout of controls in dialogs in wxWidgets because of their ability to create visually appealing dialogs independent of the platform, taking into account the differences in size and style of the individual controls. 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.

Our UK Ring Sizers use the British Standard measurements. This means that there are 26 different ring measurements ranging from letter A to letter Z. From one letter to another the ring circumference goes up by increments of 1.25mm, with half sizes in between. 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? 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. I've been doing this shoot'um'up game more than 70 years and know a bit about how to achieve maximum accuracy from powder guns...and by extension airguns. But as Bob said, the gains are small, and shooting is much more fun. If I get around to benchrest competitions I will probably use the sorted ammo, but until then shooting is more fun than sorting.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!

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. For information about the wxWidgets resource system, which can describe sizer-based dialogs, see the XML Based Resource System (XRC). See also wxSizer, wxBoxSizer, wxStaticBoxSizer, wxGridSizer, wxFlexGridSizer, wxGridBagSizer 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. Weighing and inspecting for deformation is an excellent way to reduce variability...I can reduce group sizes by half just by weighing my powder bullets...I don't mic OD's but I DO measure ogive lengths...maybe measuring pellet lengths might also help. You can reduce variability only so much and then weather or environmental factors take over...or you just flub the shot.

It is the unique feature of a box sizer, that it can grow in both directions (height and width) but can distribute its growth in the main direction (horizontal for a row) unevenly among its children. In our example case, the vertical sizer is supposed to propagate all its height changes to only the text area, not to the button area. This is determined by the proportion parameter when adding a window (or another sizer) to a sizer. It is interpreted as a weight factor, i.e. it can be zero, indicating that the window may not be resized at all, or above zero. If several windows have a value above zero, the value is interpreted relative to the sum of all weight factors of the sizer, so when adding two windows with a value of 1, they will both get resized equally much and each half as much as the sizer owning them. Then what do we do when a column sizer changes its width? This behaviour is controlled by flags (the second parameter of the Add() function): Zero or no flag indicates that the window will preserve it is original size, wxGROW flag (same as wxEXPAND) forces the window to grow with the sizer, and wxSHAPED flag tells the window to change it is size proportionally, preserving original aspect ratio. When wxGROW flag is not used, the item can be aligned within available space. wxALIGN_LEFT, wxALIGN_TOP, wxALIGN_RIGHT, wxALIGN_BOTTOM, wxALIGN_CENTER_HORIZONTAL and wxALIGN_CENTER_VERTICAL do what they say. wxALIGN_CENTRE (same as wxALIGN_CENTER) is defined as (wxALIGN_CENTER_HORIZONTAL | wxALIGN_CENTER_VERTICAL). Default alignment is wxALIGN_LEFT | wxALIGN_TOP. We would advise you not to measure an existing ring at home with an ordinary ruler or tape measure. They won’t give you the high accuracy needed to size a ring properly. If you are buying the ring for someone else, you can take one of their rings to a local jeweller who will measure it with a ring sizer tool. 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 I'm new to PCP...have a 25 cal Daystate Air Wolf coming my way and a rebuilt 22 cal Gauntlet coming from the factory both of which should be here by next Thurs...so I'm crawling the PCP net and banging away with my 177 Octane and 17-22 cal powder rifles fillling/killing time.
