Re: Neck Tension Conundrum
I've done some serious experimenting with neck tension in 22 and 6mm calibers, and one thing I learned fast was that there will be a sweet spot in the amount of tension that will greatly make a difference is your extreme spread in velocity. One thousandth of an inch took my ES from double digits (close to twenty fps) down to about seven or eight fps on a .223 case. The 6mm Remington also seems to be touchy on this issue alone, but not as much as the smaller case was. Now I starting to experiment with my 6/250AI.
