Old Sneaky here: This question has been bumping around in my brain lately so I thought that I'd throw it out and see what stuck to the wall. Given the these variables, Bullet selection (caliber and design), Barrel (length and twist), is there an optium velocity to drive the bullet to obtain optium accuracy. I understand that faster speed does not always equal better accuracy but, outsie of the "Trial & Error" method, is there any mathmaitcal manipulations to use to Predict at what velocity range you would expect optium accuracy? For example: What velocity range would you expect optium accuracy from a Lapua 6.5, 139gr Scenar out of a 24" barrel with a 1:8 twist? I'm aware that there are a lot of other variables that effect accuracy but, I'm curious about only that part of the accuracy equasion for now. I'd really like to hear ideas/opinions re: this question. THANX--SNEAKY

I just got an email yesterday from a top 1000 yard shooter. He said "accuracy lives at 3000 fps. Your 6.5 would fit there.

Many 100/200 shooters say best accuracy is 3275-3340. Some others say 3375-3425....and so it goes.

One thing you will find that too fast and too slow will not work on 100/200, 600 or 1K. Too slow generally being less than 2800 and too fast generally being over 3550.

This should narrow it down for you I hope.
