[QUOTE="Edd, post: 1511610, member: 30592"] I was using .529" for the bullet bearing surface length so, if you change it to .549", you need to add .020" to my number. The most common angle for the transition from the neck to the freebore is 45°. There are some that are different. I just did a 35 Whelen. It was 30°. [/QUOTE]
