I've been trying to find some reloading recipes for this size of bullet to use in a .223 cartridge but have been unable to so far. Does anyone have some sources I can reference for this bullet?

Pulled .223 32 grain ss190 Black Tip Armor Piercing bullets.

that's a tough one, maybe if you can't find anything, start off with some 40gr load data, usually you can stay out of trouble if you start of with data for a heavier bullet.

That's the plan if I can't find something on the 32. I was able to find some data for 35 gr.

Not sure how well they will work in .223 loads bullet is designed for mv of 2800 fps. Might find some info here.

You can use data for lighter bullets using the next highest weight bullet(within reason) It gets a higher velocity. The 35 grain data should be fine but I have no idea of that bullet in a 223

More important is the twist of your rifle.?? If it is a AR15 that light of a bullet will probably not work well.

You would need something like a 1:14 twist, like a bolt action varmint gun.

I think you really mean ss109 which are 62 grain bullets. With the steel insert, they are actually longer than 69 bthp match Sierras which requires them to be seated a little deeper in the case than comparable full lead core bullets, which requires a slight reduction in powder. Use 68 or 69 data and you should have a good safety margin.

The OP's first post has a link to the pulled bullets?

32grs seems very light for some thing that is made for
penetrating steel, in my mind...........but the .223 cal
ammo has come a long way.

Good luck finding some loads.

Nah those are SS 190... from 5.7 rounds.... they are aluminum instead of lead surrounding the penetrator.... as a previous posted mentioned, they will not go well with a rifle with "normal" twist rates.... would be nice to have for a 5.7 pistol/ P90 though....

One thing to keep in mind when loading these...
You can reload to 35/40gr specs however, they are longer then any other 35/40gr bullet. Which will reduce the amount of space in the cartridge therefore increasing the PSI. Be careful not to have a kaboom. Also remember that at a max pressure you're pushing 3800 FPS, so go easy on these... If it were me, I'd load them similar to a 55gr fmj, based on their length.

Curious to see what you develop for them...

One more thing...

As for stability, it helps to have a shorter twist, however it is not necessary.
The 32gr SS190 5.7 heads load up and shoot just fine from any standard AR. They are light, and will be affected by environmental conditions more then your average round. However, accuracy is unaffected out to 200yards. These bullets are designed for CQC, and are best when utilized inside of 100 yds.
In a defensive scenario, these bullets are not ideal, and may pose a hazard due to over penetration. in the 5.7x28 these are hot, in a 5.56x45, they are dangerously fast. (3600-4000 FPS) So be careful loading these, and always err on the side of caution.

After these posts and some research, the risks out weigh the rewards. I passed on them. Thanks for the info everyone.

I think I would be tempted to load them according to recipes given for the various 35 grain .223 bullets. I can't see any likely KB issues. Not sure I'd want to buy 500 of them without doing some testing first.

.223 Remington also requires .224 bullets, not .223, which is more common in older calibers like .22 K-Hornet, etc.

I'm new to this forum but not when it comes to loads using lighter bullets. I've had very good experiences using the V-Max 35 grain bullets and slower twist barrels(1-12 twist). While I Can't officially comment on particular powder charges I will say that the faster you push the lighter bullets in 223 the more accurate they become. Hope this helps.
