I'm not seeing where anyone quoted "your" bullet velocity, I see "a" velocity which was stated by me with roughly the "energy" for that velocity and bullet weight. I personally wasn't talking about variances for one reason, it was a simple question on a simple subject, and no one had to reinvent the wheel over it. Not sure why you're standing so close to the fire over this, but in my case, I can assure you I have more time on the trigger than you can imagine in many different fields'..., work and sports; as a former Swat Counter Sniper and LEO State Sniper Instructor, Army B-11 and E7 type Drill Sgt, NRA high power shooter, National, and International, just responding to your statement, and there are members on this forum who can verify it, and "YOU Sir?" Why don't you include your aforementioned point(s) in the post that you are referring to that way no will "have to"... second guess'..., you as you've clearly expressed. Sorry, that you're having a bad day over this perhaps things will get better.
