Well, one way that Hornady can continue to influence the quality of the loaded .17HMR ammunition is in the providing of the V-Max bullets in all the CCI-assembled, variously-branded 17-gr. V-Max loads. Hornady is, after all, primarily a bullet-maker (or has been until they started producing ammunition). As any handloader will tell you, the bullet is the most important element in the accuracy equation. I suspect that Hornady places some emphasis on the V-Max bullet production, thus helping to increase the probability of accurate rounds assembled by CCI.
There have been a number of questions over the years about whether match-grade .17HMR ammunition would at some time be available. Since there's no SAAMI .17HMR match chamber specifications, the road to higher-grade ammunition would have to come via more uniform bullet, case, primer, and charge weights. I'd really like to see Hornady--or another ammunition company--take this on. The price would be higher, but for many, it would be worth it, as it's already a great cartridge and, in good rifles, just about equals .22LR match-ammo performance. In fact, I can do as well at 100 yards with my one .17HMR as I can with my .22LR Anschutzes with match ammo. And as I noted earlier, my .17HMR does better (pretty consistently sub-MOA) at that range than the three .22WMR rifles I've owned.
