They only have so much loading equipment and setting it up for an unpopular cartridge, when it could be used to make ammo for a more popular cartridge, may not make economic sense.
So it makes little difference if the cases are shared with 22LR ammo and the bullets are available because they have uses in other cartridges. If the demand dwindles enough then you may not be able to get ammo. If you just have to have a 17HM2 then buy lots of ammo while it is available because it may not be in the future. The shine has worn off 17HM2 and only time will tell if it lasts as an available ammo.
LDBennett, you always have good info. Thanks.
