I have around 800 rounds of S&B SS109 which I got at a price which is very hot/accurate ammunition that I am very happy with. For those who don't know, S&B M193 has a thick jacket and will not fragment. Does the 62grn SS109 FMJ bullet have the same overly-thick jacket that thier M193 has which is not conducive to fragmentation? This is commonly encountered ammunition and its accuracy/velocity and price make it very appealing, provided its capable of fragmentation. Does anyone have a S&B SS109 which they could pull and photograph and compare to IMI or ADCOM M855 or similar ammunition? I don't have the means to conduct this experiment myself, but if anyone else does, I and others I am sure, would be very interested to know the results. Thanks for the help.

S&B uses steel as a jacket material, which is why it won't fragment.

I would use a magnet to check the jacket of the SS-109 that you have.  If it sticks very readily, then it probably has a steel jacket and also will not fragment.  However, I have noticed that a USGI M855 will weakly attract a magnet due to the steel used in the core, so if you can compare it to a regular SS-109 type bullet it may be helpful.  


-K

SAME JACKET AS ANY SS109 bullet!

Bullet is like all SS109 bullets NOTHING WRONG WITH THIS AMMO PERIOD

FMJ, you totally missed the boat.....While the velocity/accuracy of this ammo is superb, its fragmentation ability is unknown, which is why I asked. Standard velocity figures are based upon a common jacket material and thickness. If a bullet has a thicker jacket, it requires more velocity to fragment, and even then it may not fragment. S&B M193 is also excellent ammunition, but despite having good velocity/accuracy, it will not fragment because of its thick jacket. I was curious to see if thier SS109 has the same overly thick jacket. I was hoping someone had pictures of the base of the S&B SS109 bullet to compared to that of IMI or LC M855. If its too thick to adequately fragment, then that isn't necessarily a bad thing as this could be an asset in some media. I will have to do some additional testing of my own to investigate these possibilities.

Thanks for the heads up warning on this stuff.  I was just wondering about ordering some from Centerfire when I read your post.  266.

SAME THICKNESS AS MOST ALL SS109 that I have took apart! Lake city M855,Win M855,Santa Barbra SS109 etc!

I think you misssed the boat buddy!

THE S&B M193 has a thick jacket!

NOT THE SS109

Better yet Pull the bullet SS109 and compare to Lake city or win M855?  SAME

Then you will know that the jacket is fine!!!!!!!!!!!!!!!!!!!!!!!!!!

THERES THE BULL SHIT GUYS START SPREADING

M193 is the thick metal S&B you are speaking of?
