I am going to be reloading 30-06 and 300 win mag. But one thing that I noticed, in my manuals all the info for the 300 win mag is based on a barrel that is 24" long. The gun I will be loading for is 26" long. Does that increase pressures or change the way that I should reload? I know that there will be increased muzzle velocity, but I can't find anything anywhere in the book or the internet about if this changes pressure. If somebody on here could lend some of their knowledge I would greatly appreciate. I don't want to blow myself up.
That being said, I just got everything I need for reloading. I still need to build a bench before I can start, but I have been reading everything I can to learn about reloading. I picked up the rcbs rock chucker kit and a few other things. I can't wait to start. All that I do now is read about reloading.
