I've had 1000-yard groups where some bullets that left faster than slower ones print lower and slower ones print higher than the higher ones. Difference isn't much, only a couple inches.
To answer your comments 1st one; I'm not an expert at internal ballistics, i'm reporting information I have gleaned and others in the industry have gleaned over years of work with thousands of custom barrels. I could give you my theory on this but likely it would just raise more illogical questions from you. You obviously didn't read the entirety of my article and the follow up discussion or you could have answered that from that info.
2nd. I never said faster bullets will cluster tighter, no one in the thread has stated that other than you. So what is your misconception about all this that you have these preconceived notions in your head which are so misleading?
3rd Your 1000 yard groups are affected by so many things that it is impossible to dictate what causes this or that. Your ability for one, condition changes as far as wind direction and velocity for 2, your ability to load ammo for 3 and I'm not just referring to speed of projectile but all the intricacies of brass prep and bullet run-out ect. Scope parallax, mirage, the list goes on.
So what is it that you concluded in your testing since you fail to account for anything other than the speed of the bullet?
