I looked for this in the archives but could not find it.
A box of factory shells broke the 100.00 mark so I'm biting the reloading bullet. I purchased a RCBS master kit and familiarized myself with all the components. Everything was great right up until I got to the COAL. The manual gives a rule of thumb measurement which is .045 different than a factory load, but says this measurement needs to be taylored to my gun. I'm reloading my Wetherby 30-378 which I understand has a free bore chamber. So where does a guy start on bullet depth???? If this is a dumb question, please be gentle.
