Hey, my tongue-in-cheek answer was just that ...
During a couple of my armorer's courses we were advised to use care in adopting some types of frangible ammunition, because depending on how the bullet & "jacket" are made, some frangibles may offer the potential to accelerate barrel wear. No recommendations were made, just a disclaimer & precaution to look into it in some further detail if we were called upon to make any recommendations for our various agencies.
The other issue you often hear about is how some frangibles may also use lead-free primers ... or supposedly use cases which have primer pocket flash holes which may not allow for consistently "sufficient" ignition of the propellent.
Something you might look into is one of Winchester's alternative handguns ammunition lines, such as the Super Clean NT Non-Toxic or Ranger Frangible ammunition lines.
I haven't used either of these ... and a Winchester rep didn't send us enough rounds of their Winclean ammunition to make any determinations (3 rounds in a baggie??? A promotional mailing, it seems ...) if we wanted to try it, the price notwithstanding.
The Super Clean NT uses a ductile tin core bullet that's advertised to reduce the possibility of splash back towards the shooter, uses their lead/heavy metal free primers, and clean buring propellant.
The Ranger Frangible uses a nylon, tungsten and copper composite bullet that's lead free, and their lead/heavy metal free primers.
I'd imagine the SIGArms Academy wouldn't be using anything that would be "disadvantageous" in their weapons, or the weapons brought to the classes by the students. They have a good reputation, you know.
After all the years we've incorporated metal targets into our training, and some outside in-service training I'd attended, I'd think that anything offering the potential for reduced bullet material splash back at many "closer range" distances would be worth it, "prevention-wise". "Safety" & "Prevention" are a couple of terms that CAN be combined ... and should be ...
I remember once attending an instructor's course where I was shooting an MP-5, using the provided 115gr STHP ammunition, and discovered my jeans were being peppered by bright silver colored fragments as jacket (& bullet core material) was being splattered back at me. Hmmm ...
Now ... "affordable" and "frangible" used in the same sentence, setting aside any supposed "reliability" issues aside? I'm not sure if those 2 ideas have yet been consolidated into a single product ...
Anybody?
Privately owned ranges can sometimes offer some differing "restrictions", which may not always seem "user friendly" ... but when it comes right down to it, it's their range ... and their range equipment ... and their insurance carrier.
I haven't used a public range for shooting in several years, although I'll occasionally buy ammunition if I want something we don't stock at our agency range. The gross safety violations I sometimes observed at some of our local ranges just scared the daylights out of me ...
I DO realize, however, that once I retire I'll probably not be able to use the agency range anymore ... as I plan to move ... so I'll have to find a public, or "private" club-type, range in order to continue my personal training. I may, or may not, decide to remain actively involved on training other folks ... but I hope to find at least one public range where I can meet agreeable, pleasant folks who enjoy all aspects of shooting activities & related recreational pastimes ... and where I feel safe walking in the front door.
I'm not imlying that I necessarily feel "safe" standing on the range with other cops, either.
:banghead:
Some of the nicest and most interesting folks I've met during my activities as an agency firearms instructor & armorer have been the folks attending the CCW classes. I've often found an opportunity to fit in some "extra range time" with a few folks from these classes, from time to time, and would enjoy the opportunity to work with some of them a bit more on some private range ...
Sorry ... I didn't mean to side-track your thread ...
I'd be interested in hearing if you discover some frangible ammunition which fits your needs ... as we just haven't decided to get involved with any of it at this time ... but I'm always interested to learn something new.
