Does anybody have a ballistic chart for this round out of a 24 in barrel?

I would really appreciate it.

Mk 262 is probably doing ~2900 fps out of a 24" barrel.

Mine were doing 2850 out of a 24 barrel in cool (20 degrees F)weather. In warmer temps, the 2900 might be real close.

My 223 5r with 24 in barrel has them over 3050 fps. My krieger 1-7.7 20 in SR has them at 2850. What barrels are you guys using?

I have a 20" Noveske, but I don't shoot the Mk 262 (I hand-load). I just took a guess based on my knowledge.

Thanks for the data guys, I shot 100 rds of it yesterday. 2.4 in high a 100, and I was smoking prairie dogs at 300 - 375 yds, no problem. Not the ideal round for this application, but man was it fun....
