Re: 30" vs. 28" vs. 26" barrells on 30 cal. Wby\'s
Northernsniper, not an exact science but there would be little gained by going to a barrel only 3" longer. About a 50 to 75fps gain and that assumes that load still shoots accurately enough. Different barrel, who knows what it likes.
To reach your 3000fps goal, take JonA advice, use a bigger case. That way you have the case capacity to reach that vel without stretching the pressures. In general, best accuracy is reached around 90 to 95% of max pressure.
Also, unless you plan on reaching out a long ways, that extra 125fps really will not amount to much as far as on game effectiveness. At best, it will give you the same impact energy 100yds further downrange.
As long as the bullet arrives with at least 1700fps, no grass eater is going to complain. That pretty much defines max distance for consistent, reliable, bullet expansion for that bullet. If anyone has tested or has experience at slower impact vel with this bullet, please let me know. "softer" bullets can work at slower impact vel and still do the same thing.
