Speer 9mm TMJ for Indoor Ranges

Speer offers its Lawman 9mm range ammo in total metal jacketed (base enclosed) form at a very reasonable price. It also offers this round in a "clean fire" form--the difference being a lead free primer and about $5 more per box. My question: Is the primer a significant source of airborne lead? Thanks-- c

Hello. I may be remembering incorrectly, but I think that something called "lead salts" are emitted from regular primers. How significant it is or isn't, I do not know.

Though I suspect it has probably changed, I had some Speer TMJ (early-90's vintage) with lead-free primers that would not fire reliably from any striker-fired pistol in which I tried it, specifically Glock, Kahr and S&W's M&P. This ammunition had been stored inside under central air and heat and worked fine in my hammer-fired 9mm pistols and grouped well.

Best.

Corky -
Most modern primers use lead styphnate, so they are a source of lead.

Thank you, gentlemen, for your responses. I asked the question as I am limited to indoor range shooting and am doing what I can to decrease lead exposure. It was my understanding that lead bullets and even FMJ rounds with a lead exposed base were the chief source of airborne lead vapor. I am searching for any infomation I can find regarding primers as a significant source as well. Should you come across any relevant data, I'd much appreciate your letting me know. --c

Mr. Camp, My Web search has come upon this comment relative to lead-free primer life. How long had your lead-free ammo been stored?

". . . lead-free primers have a shorter lifespan then conventional pistol primers. While the conventional primers will work after literally decades in storage, I understand that lead free primers have a shelf life somewhat under a decade before they become unreliable. Since I never let this ammunition sit this long before use, that has never been a problem for me."

Hello. It had been stored over a decade. At the time, I was assured that the primers were "just as good and better" than conventional.

It appears maybe not, doesn't it?

All of the ammo did fire, but only after the hesitant rounds were shot through my Hi Powers or other hammer-equipped 9mm pistols.

Thanks for the heads up on the leadless primers.

Best.

PS: I got "curioser and curioser" so I took 2 boxes of this ammunition to the range. All 100 shots fired w/o incident through an FNX9 pistol. I think that the primers may not be as sensitive as "regular" primers and that the striker-fired pistols just didn't smack the primer as intensely as pistols having hammers & firing pins. I've seen the same thing when firing 5.56mm ammo in my AR (internal hammer-fired) and then trying to do the same in a CZ bolt-action...which uses a striker. Both work fine with commercial non-military ammo. Likewise, my Glocks and every M&P or Kahr I've seen has fired any and all American-manufactured ammunition I've tried in them.
