Thanks hemi for good reply on the subject. I've never run factory ammo through my chrony but Mule Deer seems to have studied the factory load speeds and even took the cartridge apart and weighed the powder and stuff like that. He must be one of them mad scientist types with a big laboratory in his basement. LOL

If you follow the loads and recommendations in any of the reputable reloading manuals you will never get yourself in a problem. Trim to length and measure every cartridge-never speculate that if one is the right length that the other 19 will also be. Very wrong.
If you want to see very dangerous situations don't trim your brass and let it grow and grow until it will actually bind or pinch the bullet and then you can have a problem.


It is better to be judged by 12 than to be carried by 6.
