Re: 105gr berger VLD
I bring the Greenhill equation here as a conversation point and just that, a quick check or a place to start. Certainly not an absolute. Backwoods83 also makes a good point about turning faster. For the next step, lets combine the two thoughts. For example, lets say a particular caliber/bullet combo works out to a 1 in 10, then I would be thinking 1 in 9.5 or 1 in 9.
I'm sure there would eventually be a penalty to pay for turning too fast such as centrifugal force tearing the bullet apart. One of my friends who shoots benchrest comps swore a gun he had, did this.
