I am looking for some help from you guys to make sure I am doing things correctly. I took one of my once fired brass and just gave a bit of a squeeze to the neck so it would hold a bullet snugly. Carefully placed it into my bolt action and slowly closed the bolt. Then carefully extracted the bullet. I did this twice. I ended up with a COAL of 2.877. I was planning to reduce the length by .015. Is my logic correct? I am reloading with IMR 4895. So far, my most accurate load was at 43.3 grains, so I am not near any max load. Is it fair to assume that I will have some increased pressure because there will be less jump before getting to the lands? So far I have only loaded at a COAL of 2.770, which was matching a factory COAL. I know the books say that 308 COAL should be 2.80 but everything I have read leads me to believe I should determine length based on my rifle.
Thank you . Pete
