[QUOTE="smithjasona1978, post: 1787464, member: 91693"] So first I'm a noob. Not new to shooting just to reloading. I need help understanding my cartridge max overall length and the impact it has on pressure. I have a new Weatherby vanguard in. 300WBY mag. I have been shooting factory ammo in it until recently. Now I'm ready to start reloading. And my question is what should my oal be? I have a huge amount of length to play with. I can go from factory oal all the way up to 4.0 inches. 4.0 is my rifle using Hornady 208 grain eld-x touching the lands. Remember Weatherby freebore. Max I can load and have caliber diameter in the case neck is 3.85. So that still leaves me roughly a quarter inch of length to play with. And I am Also a speed freak. I want as much velocity as I can get. So should I just find the most accurate load that I can starting at the 3.85 and work incrementally shorter until I find the most accurate load? I need a starting point. I did my first round of load development at 3.75. But my manual has the length at 3.56. And the differnce in length has caused me to blow 2 primers. [/QUOTE]
