Talking about anything as it relates to cartridge collecting is fine in the forum, and legislation affecting ammunition possession, storage, shipment, or restrictions on types of, or abilities of ammunition certainly fits the bill.
I for one don’t see how anything could get through the House since there are a fair number of democrats who are against gun/ammo control of any relevance including my northern Maine district’s Rep. Michaud (one of the few democrats to have an “A” rating from the NRA).
Having executive orders and certain governmental organizations re-evaluating their interpretations of existing laws to further restrict ammunition is another matter, and they could seriously hamper things in terms of shipping, lead-content, hazmat issues, destructive-device interpretation, and also redefining what constitutes things like “importation”, “manufacturing”, or “dealer”. A classic example would be when on Feb 2nd, 1994, ATF director John W Magaw and ATF Clinton-era bureaucrat Terry L Cates decided to take on 7,62x39 and .308 steel core ammunition and absurdly define it as “pistol-caliber armor piercing” so as to have it fall under the auspices of the 1986 federal law. They did this by pointing out that there were in existence some “pistols” from the likes of Olympic Arms which were registered and sold as pistols, and which could fire the 2 calibers in question. This was done without congressional action or approval, and did not require any and meant that all imports of inexpensive Chinese and other cheap 7.62x39 ammo with steel cores intended for the commercial civilian market had to cease (on a commercial importation level).
The effect of this was predictable with Ex-post-facto allowing all existing millions of rds to remain legal, and it did absolutely nothing other than to make such ammunition progressively more expensive over time, and it certainly did nothing to dissuade 2 shooters from using this very type of ammo in the North Hollywood bank shootout of 1997. Ironically, by using FMJ steel-core ammo from their AK’s, they saved the lives of all whom they shot (not one person died), but if they had used less “objectionable” ammo with hunting style soft points, hollow points, or even frangibles, then they would have killed many due to damage caused by such projectiles above & beyond FMJ penetrators which tend tend to not fragment or expand in this caliber type.
As a collector, one might consider some possible future restrictions with such cartridge / munition types as:
37mm / 26.5mm loads
Subsonic loads meant for use with silencers
Any flechette or flame type incendiary load
.50BMG of any type
5.56 M855 penetrator type loads
Anything capable of over 1500 fps fired from a 5" barrel
Anything that is marked or marketed for “law enforcement use only” as can be bought frequently online
Any contract overrun from domestic manufacturers that was originally intended to fill a government contract (Federal & Winchester white boxes)
Any government surplus
Anything that is already illegal in California or Washington D.C.
Bringing ammo in from outside of the country
You might think that it is unwise to print a list like this, but rest assured - the anti gun / anti-ammo elements already have volumes upon volumes of legislation already written and printed, ready to inject into congress when the opportunity presents itself. If the house were Democrat controlled then it certainly all would be.
All that being said, I would give at least 2 to 1 odds against anything of any real relevance actually happening as far as ammunition possession goes. Still, a chance remains, now more so than in previous years since the public opinion polls always sway in favor of more restriction after a tragedy.
I would also caution any collector here from doing what happens on so many gun forums in terms of hyper-criticism of the BATFE. Although I point out an example of what this agency can and has done, the agency is vast and can by no means be defined entirely by the actions of a few presidentially-appointed executives or bureaucrats over time. The BATFE has always been relatively quite good to the IAA.
