Over the past few weeks, we presented our survey of rifles cartridge availability and its findings, then did the same with our survey of available and new chamberings. We drew independent conclusions from each survey, assuming, in general, that cartridge availability and rifle chambering availability were related. It is time for us to put this assumption to the test: how do cartridge availability, rifles availability, and new chambering availability relate to each other?
To evaluate graphically how they trend with respect to each other, the best way for us to do this is to normalize the availability of each cartridge, rifle chambering, and new rifle chambering, so that we are only dealing with percentages across the whole market, rather than absolute numbers. The following chart displays what the data looks like, when viewed as percentages.
For each cartridge, the chart displays, in green, the % of ammunition SKUs (Stock Keeping Unit, i.e. the specific combination of brand and type of ammunition that uniqeuly identifies the item) available for this cartridge as a % of all cartridge SKUs available, in red the % of new chamberings available at Bud's as a % of all rifle chamberings available at Bud's, and, in blue, the % of rifles chambered in the cartridge available on Gunbroker, as a percentage of all the rifles available.
If we review this chart, we quickly realize that:
- ammunition availability and rifle availability for that cartridge generally trend together
- ammunition availability and new chambering availability generally trend together, but not as well
- ammunition availability appear to trail Gunbroker rifle availability, which, itself, trails Bud's new chambering availability (we can find this out by looking at new or newly popular cartridges, and by old fashioned or obsoleted cartridges)
In this light, we can draw a few specific conclusions:
- Available now, gaining in popularity: 17HMR, 204 Ruger, 22-250, 243, 25-06, 270 Win, 270 WSM, 7mm-08
