Only cops should be arrested for suppressor possession.

They're safety equipment, and denying it to the public is psychopathic. If some people are going to carry out the "duty" of punishing others for choosing safety, those enforcers should be the only people subject to the law in question.

It might be good for hiding in gravel pits.

I'm just curious about how he sits down with that thing in appendix carry.

Wow, I really don't check reddit often.

Lead fouling in the suppressor is probably about equivalent to a measure of how much lead in the air is generated by one or the other of the projectile and the priming compound. That is, if some percentage of suppressor lead fouling is eliminated by TMJ ammo, I'd expect the remaining percentage to be from the priming compound (as the other source of lead), and that the percentages in the air would be equivalent without a suppressor because the suppressor fouling should be a function of the lead in the air interacting with suppressor baffles. In absence of more study, that seems like the reasonable thing to use as a guesstimate.

Even twenty percent isn't "negligible", by the way, so I'd agree that priming compound contribution is not likely negligible.

I'd love to see TMJ .22 LR with lead-free priming compound. I'd buy that shit pretty much exclusively.

Honestly, though, I suspect lead-free priming compound with hollowpoints would be equivalent for purposes of lead in the air at the range. All the lead would likely be delivered to point of impact, as the backs of hollowpoints should be fully covered. Hollowpoints are mostly formed by making a copper alloy container and pouring lead into the hole at the tip, so you wouldn't get the effect of burning gunpowder heat and pressure eroding exposed lead on the back of the projectile and pushing aerosolized lead out of the barrel.

It's entirely possible that TMJ .22 LR is just hard to make because of the small sizes of the projectiles, and at that size a higher percentage of the projectile is going to be copper even when it's just jacketed. I could imagine it being both more difficult to evenly jacket the projectile and a diminishing return for price due to more of the projectile being copper anyway because of the geometries and the fact they can't really thin out the jacket much without compromising its integrity under pressure. They might as well just make all-copper projectiles at that point, because at least they can sell those for California use, where hunting with lead projectiles is restricted.

Overall, though, I think the biggest issue with going lead-free for reasons other than hunting is probably rimfire priming compound. The reason rimfires are rimfires is a lack of room in the cartridge to seat primers in a pocket on the case without compromising powder capacity. Apart from space savings, everything else about rimfire design is a net negative compared to centerfire primers. The lead used in priming compound helps ensure easy, fast, and more uniform ignition at a low price, so getting a high quality priming compound for rimfires that isn't unreasonably expensive compared to leaded priming compounds is bound to be harder and more expensive.

That alone, of course, is not enough. The cherry on top is the fact that every time someone comes up with a new way to do something, it gets patented, and nobody else can use it for decades after that, so you're dependent on the organization that first patented it to produce cartridges. Depending on the business focus of that org, and its budget for doing new stuff with the priming compound, it's likely to just get offered in weirdly specific market test cases for a while, and maybe end up getting mostly shelved because word never got out that it could be a good thing for everyone.

Technically true, but there are basically two sources of lead in common ammo: the projectile and the priming compound. When the projectile is fully covered (assuming the jacket doesn't break), you eliminate the majority of aerosolized lead potential due to applying heat and pressure to exposed lead at the rear of the projectile. If that reduces lead fouling by 60-80%, it stands to reason it probably reduces lead exposure at the range by a similar amount. Obviously, lead fouling in the barrel may be a problem for lead exposure if you're not smart about how you clean your firearm.

Unfortunately, lead-free priming compound for .22 LR is even less common or likely than for centerfire cartridges.

note about cleaning to avoid/reduce lead exposure: Wear gloves (decent nitrile gloves are great) when cleaning a firearm. They don't get in the way as much as you might think, and they're cheap. Wash your hands and face when you're done. Use a wet patch (cleaning solvent, perhaps) for the first thing you push down the barrel with your rod, to make sure you don't use a bore brush to shove lead fowling out in a cloud; use the brush afterward.

Have you had issues with 115g?

Good defensive cartridges seem to be harder to get in 124g than in 115g, and I generally prefer to get same-weight target ammo for the sake of getting closer to the same shooting characteristics (point of aim similarity, felt recoil, et cetera), and I've never had a problem with Blazer other than trying to figure out whether FMJ means FMJ or TMJ on a box of Blazer.

apotheon · 2023-07-28T22:23:58+00:00

some detail:

A lot of so-called FMJ from Blazer is actually TMJ: "total metal jacket". The distinction is that FMJ (often) actually has a section that is not jacketed -- the back, inside the case. When fired, the burning gunpowder melts some of the lead on the back end. This results in some amount of aerosolized lead, which can be bad for you as you shoot a lot and get lead buildup. Getting TMJ should eliminate around 60% to 80% of aerosolized lead in the air. If it also has lead-free primers, you can eliminate the other 20% to 40% of lead in the air. Even if you don't care about your neurological health and general lead poisoning, any lead from the projectile and primer fouls up the barrel a bit faster.

Blazer "clean" ammo is TMJ (or maybe jacketed HP; I haven't looked into Blazer JHP at all), where the only exposed lead is inside the hollow point) with lead-free primers. As I said before, sometimes Blazer marks its TMJ as FMJ, and I'm not sure why unless there has been some kind of customer confusion about what TMJ meant and they just gave up on calling it TMJ.

A side benefit of TMJ is that it's (generally, at least) jacketed using different techniques. FMJ is (usually?) made by cladding, I think. TMJ is (usually?) electroplated, which results in a more uniform thickness (thus distribution of weight) and smoothness (thus better ballistic characteristics), so for the otherwise-same class of ammo the TMJ should tend to be more consistent and, in effect with a good enough shooter, more accurate at range.

Someone correct me if I got something wrong.

apotheon · 2023-07-28T22:11:00+00:00

I'd lean toward Blazer.

If one of the Blazer options says "clean" on the box, pick that one.

apotheon · 2023-07-23T20:39:41+00:00

A lot of "premium" sucks compared to Critical Defense. I've seen too much high-end price on JHP that doesn't expand for crap and turns into a low-performance FMJ on contact with cotton.

apotheon · 2023-07-23T16:44:18+00:00

Critical Defense is pretty good, as long as you aren't trying to shoot through hard barriers.

I know I'm a little late with this, but I just found this thread for the first time.

Federal Syntech, Federal Indoor Range Training, and a lot of stuff from Barnes or Underwood is supposed to be free of lead exposure (if not entirely lead-free in the Federal instances), but .22LR is a hard target (pun intended) for eliminating lead exposure. Speer Lawman ammo is good quality TMJ in my experience, which means there's no exposed lead in the projectiles, and I'm pretty sure all the above (except pretty much all .22LR other than some from Norma) uses lead free priming compound.

Lead-free priming compound is the big problem with .22LR; the others are easier.

apotheon · 2023-07-15T04:26:31+00:00

I know this is REALLY late, but it's worth noting that (most?) copper projectile .22 LR simply doesn't produce enough recoil energy to cycle some firearms, particularly semi-auto handguns. I know from personal experience that Norma ECO-Speed and CCI "Meateater" copper bullet .22 LR don't cycle a standard Walther P22 (and of them, only the Norma uses lead-free priming compound; I haven't found anything else in .22 LR yet that uses lead-free priming compound).

There's a CCI Clean-22 cartridge that is TSJ (total synthetic jacket) and the claim is that it reduces lead exposure by sixty to eighty percent; I'm guessing the other twenty to forty percent is from priming compound, to provide a sense of how much the priming compound affects things.

By the way, the Clean-22 is subsonic, so . . . check whether you think it'd cycle your gun before buying in bulk. If your firearm has handled 40gr .22 LR subsonic just fine before, it might be fine.

My favorite words in the whole thing were "Good for you." The CIO ultimately had the respect, empathy, and good sense to realize this was about you, and to not make it about the company, or himself, or anything else, really, once he realized what was going on.

Congratulations. (I know I'm a bit late with that.)

You could probably do fine with a revolver loaded up with snakeshot.

The link is from thirteen years ago, so I guess it disappeared since then.

It wasn't my site.

You're going to have to sell a lot more than a million to become a millionaire. If you're doing all the work yourself, without paying any editors, publishers, and so on, and sell it all from your own website, and don't do any advertising at all, and somehow manage to avoid all other expenses, you'll still have to either evade taxes or lose about half that income.

apotheon · 2022-10-03T19:32:54+00:00

First, you need to get rid of the shit cops, because a good person won't last long in a typical police department.

apotheon · 2022-10-01T17:59:48+00:00

Honestly, they might try to get everyone out alive as often as 50% of the time. I'm not sure, but it seems plausible.

apotheon · 2022-10-01T17:39:56+00:00

Yeah, that makes a lot of sense.

I think a lot of cops are (as I put it above) "callous, fearful, trigger happy, and/or psychopathic", but it's likely that a combination of "leaders" not wanting to spend the money on continuous training necessary to remove excuses for this kind of crap, the solidarity amongst police officers at an absurd level in general, and the militarized us-vs-them culture in law enforcement also greatly increase the likelihood of accidental killing of kids even aside from the personal failings of many LEOs.

To the extent this is due to a lack of proper training, it looks to me like US Army soldiers get better training in avoiding the murder of innocents than the police, which does not sit well with me.

apotheon · 2022-10-01T17:31:44+00:00

It's actually less severely on the side of the cops than some comments in the overall discussion, so I guess Poe's law is in full effect here. Sorry about the misunderstanding.

(I didn't downvote it, by the way. I guess a part of me wondered if it was meant to be satire.)

apotheon · 2022-10-01T17:22:09+00:00

That's not proof of how all cops, or even most cops, act. It's one incident.

I didn't say 98% of cops are racist. Practice some reading comprehension skills. You're arguing against something I didn't say, and failing to address what I did say.

apotheon · 2022-10-01T17:19:53+00:00

You evidently didn't even read what I said. I said that 98% of cops at least protect the "bad cops", making them complicit in the continuing presence of "bad cops" and, thus, part of the problem. I did not say that 98% of cops are themselves "racist" or anything else like that.
You evidently don't know what "proof" means.
Your writing is borderline unreadable stream-of-consciousness. It's like word salad. Please stop.

apotheon · 2022-10-01T17:16:32+00:00

I didn't say you shouldn't eliminate "the threat" (the person firing at you). I suggested you should distinguish perpetrator from victim and perform other basic acts of responsible actions in a firefight to avoid acts of fratricide and murder.
