There was a fairly broad selection of .30-06 high power rifle cartridges tonight. It seems the .30-06, which was the standard US service rifle and medium machine gun cartridge from before WWI all the way through the Korean War, has become so obsolete now that even the civilians largely ignore it. There are plenty of good .30-06 rifles around, so if you've got one and want to shoot, looks like you should be able to find ammo for it.
Common high power deer rifle cartridges like .270, 7mm, .300 WSM are still gathering a bit of dust on the shelves. There's a lot of cross-over between hunters and defensive and recreational shooters. Often enough the hunter may own an SKS or an AR-15 and those who are primarily defensive and recreational shooters often own a common deer rifle or bird gun. However, there are hunters who have relatively little interest in the Second Amendment and plenty of Second Amendment supporters who have no interest in hunting. Gun prohibitionists have been working to drive wedges between the hunters and the shooters for a very long time. The NRA pubishes two membership magazines -- one written for hunters, and the other written for defensive and recreational shooters. So, this is an important feature of the social and political landscape.
Talk of banning "armor piercing" ammunition is more effective at uniting the shooters and hunters than anything else I've ever encountered. What the gun prohibitionists don't want the general pubic to understand about such legislation is that it would ban almost all rifle ammunition, some handgun ammunition, and probably shotgun slugs as well. Large shotgun slugs are remarkably penetrative. A 12 gauge 1 ounce common shotgun slug will sail right through a shockingly thick plate of "bulletproof glass." Guns are by their nature penetrative. The fact that common rifles and shotguns will defeat some types of body armor should come as no surprise. Traditionally, the police officer's ballistic vest has been selected to stop a bullet from his department's issue sidearms -- because when they get shot, it's quite often with their own gun (one of the hazards of open carry). They're generally not issued armor made to stop rifle fire. Rifles are seldom used in murders of police officers. Military pattern semi auto rifes are rarely used in any murder. And to date, no legally registered fully automatic weapon in the US is known to have been used in a crime. Fully automatic weapons stolen from the military and law enforcement or illegally obtained or manufactured have been used in crimes here in the US, however.
