BL, no worries, you made me wonder if I had been sleeping in class again.
I have been told that the BH Mk 262, Mod 1 special issue 77gr. BTHP-M launches at more than a hundred fps faster than the BH 77gr. I tested. Part of the reason for this is that the 5.56x45 NATO is loaded to higher pressure limits than the .223 marked ammo. As I mentioned, I will try to get velocity readings on the M193, M855, and Mk 262 next time I am on the range and have time.
The same source also told me that the Mk 262 will frag at velocities as low as 1900-2100 fps in ballistic gelatin, which if it also does the same in live tissue, should give it better performance than I anticipated.
This is turning into a science project.
