Frangible Subsonic?

Post by Jed Depew » Mon Jun 06, 2016 12:35 pm

Please help my ignorance. I seems like a frangible subsonic would be an ideal suppressed round, the limited range of a subsonic would lend its self to closer shooting conditions and the lack of a ricochet from a frangible seems like a perfect match. But look as I may, there seems to be nothing like this out there. There are some "controlled fracturing" subs which are closer but I have yet to see a dedicated frangible subsonic offered. Now I can not be the first person to think of this, so my guess is that there is a very good reason not to use a frangible sub on a suppressed firearm but I am damned if I can figure out what it is.

Please, educate me. I am obviously missing something.

Welcome, and thanks for the thought provoking question. 8)

In certain situations, it sounds like it would be a good choice .... BUT, I'm sure someone way more knowledgeable than me, will tell us why it's not. :lol:

Yeah, those Lehigh Controlled Fracturing rounds are some mean sumbitches. :twisted:

Frangibles are shit for ANY situation outside of a shoot house(where they serve a VERY good purpose). Even guys such as Air Marshals and the like do not carry frangibles.

There is a reason why bullet manufacturers have spent millions of dollars(probably billions of dollars) attempting to get bullets to expand, yet retain all of their pieces and weight because when you start to lose pieces of the bullet(fragmentation), you lose that solid direct energy transfer. You want maximum energy transfer, not energy dispersion.

You also need minimum penetration depths. If you look at enough bullet tests in gel where you see bullets that came apart(fragmented) instead of stayed together, those fragments will generally be retained very shallow in the block and will not have reached the minimum penetration distance.

For the sake of discussion, it would be tough to make a bullet so fragile that it would blow apart at those speeds. Maybe one made of stale biscuits? :lol:
Maybe something like a Glaser Safety bullet as they are made for 45 ACP - not exactly frangible but close.

DRT Ammo would be the exception to the rule.
They have a powder metal core that has excellent penetration in all their rifle and handgun varieties.

I have tested their .308, 300 blackout, various.223, and the .380, 9mm, and .40

It is hard to find a barrier blind "Frangable" bullet and they did it.

It is the only Frangable ammo I buy but that's just me.

That all being said...DRT is working on a subsonic 200+ grain bullet that will expand. I have that directly from DRT and I am a member of their Industry Pro Team.

If something sucks I would tell them and seek out someone with more knowledge than I have to verify my findings before I would publish. Good folks. DRT does not offer free ammo in exchange for positive reviews.

I use sinterfire bullets in my FN FiveseveN, and they work just fine. I've loaded a few in my AR as well, they made round holes in paper. They are light for caliber. I'd guess if it's a single shot you might be ok, but I have no idea if they'd be heavy enough to cycle an AR. Heaviest they list are 125s. My concern with shooting them through a can would be if one 'franged' in the bore. I hear if you crimp them too heavy, they will break in half. Mine have all passed the whack test. I did notice they make a .458 bore though, that's got me thinking about my SOCOM...

Making bullets is a lot harder then 99% + of people think it is.

having worked with 3 small companies trying to bring an affordable expanding sub to market. I can tell you there is a lot of money that goes into development. Add on to that government fees and charges, it makes it very expensive to have a dedicated line to any bullet that is not already standard.

I have been shooting M160 frangible bullets for years in the Blackout, subsonic suppressed. Not enough oomph to function semi auto, I normally shoot them in bolt action or single shot firearms. I also use them on armadillos at night with a thermal sight.

Some gun and powder combos give fine accuracy at supersonic speed. My FAL loves them in the 2000+ fps range, but most guns do well in the 1700 fps range.

I wonder how it is going to do against a soft target.
