Ok we all know how critical seating depths can be with various bullets ,small changes can make tremendous difference in accuracy. My question is why ? If you could fire a rifle and freeze the bullet as it exits the muzzle what distinction will be noticeable on the jacket ? If its jammed into refiling will the jacket be visibly distorted or if its seated as to jump into rifling will it be scar less ? Isn't the bullet swagged to new dimensions during its journey down the bore ? How does the bullet know how deep it was seated ? How does it affect accuracy ? I guess what I'm asking is
What the HELL " ?
