I'm trying to understand why does the overall length of the bullet vary so much?
I'm reloading .40 cal and using 165 grain ball ammo with Unique powder and cci primers.
I noticed the OAL between the 135, 155, 165, and so on varies quite a bit. I noticed this with some 30-06 guides too.
So why is this? I thought the overall length was supposed to be a set length to fit the gun chamber.
How does this vary from pistol to rifle and what's the rule of thumb for OAL - just follow the instructions?
Thanks!
ps - sorry for such a noob question - just trying to understand.
