[QUOTE="Lou270, post: 1941988, member: 5352"] 3.1+ would give more case capacity. The neck on 270WSM is .2765 (about 1 caliber). For everything you seat beyond about 3.06 you are moving boattail into neck section and reducing amount of bearing surface that is gripped by case neck. May or may not be important to the individual reloader, but 1 caliber is a pretty standard rule of thumb (300 win proved this wrong). I have some 170VLD but not measured them to see how they compare to the data in spec sheets on the website so actual may vary if that info in tech reference sheet is not accurate. [/QUOTE]
