Grouping satisfactory?

[Bart B]

Excellent bullets shot from excellent barrels in excellent condition rarely have any nutating or base and tip spinning around their trajectory axis regardless of how long they are. And those that do typically dampen out in the first 100 yards anyway. And unless the barrel's crown is bad or the bullets are quite unbalanced to begin with, they will fly downrange with their long axis tangent to (parallel to) their trajectory all the way to the target.

Read Sierra Bullet's Rifle Reloading manuals for what's probably the best info on this I've seen.

Bench or prone and how heavy is the gun?
I shoot prone bipod with a firm hold and cheek weld and pre-load the pod. I try to be consistant and get it the same every time. For me this works better than a bench, I guess because I'm used to it and mainly shoot this way. A change in technique will show on paper.
I use an Eagle stock pack

Rifle weighs 14lbs, I shoot mainly from the bench but I also shoot prone.
