Like the title says, what does OTM mean? I have seen it before in regards to several ammuntion selections, and hoped you guys could educate me in its meaning. I thought I was pretty well versed in most terms, but this one elludes me.

Example:

NOTE: For general purpose LE use, if stuck with 1/9 twist barrels, the heavy 70+ gr match OTM loads are not universally accurate in all rifles and the 69 gr SMK OTM, the 68 gr Hornady OTM, the Winchester 64 gr JSP (RA223R2), or one of the new Federal 64 gr TRU (223L) JSP, Hornady 60 gr JSP, or Nosler 60 gr Partition JSP's are the best choices to most likely run accurately in the majority of 1/9 twist rifles. You are screwed with 1/12 twists, I would probably choose the 55 gr Federal bonded JSP load (Tactical--LE223T1 or identical Premium Rifle--P223T2) in order to ensure adequate penetration.


the above excerpt was taken by a post by DocGKR on Tactical Forums about 5.56 duty loads.

Thanks in advance for the info!
