There should be some difference in bolt thrust depending on bullet weight, right?
How about if I rebated the rim on the 6.5? If I turned it down to .440 it wouldn’t lessen the force on the bolt face, right?
NO AND NO
the bullet weight has nothing to do with it the pressure is the number you use. Now if you were calulating recoil then the bullet weight has a big factor.
as far as rebating or adding a rim it will not change the the amount of bolt thrust. you actualy need to use the inside of the case ID to do the caluclations. think of it this way if you were to jack up your car with a bottle jack and you placed a board under it and had 2000 pound of weight on the board. then placed a smaller board between the jack and the original board you would still have the same weight on the original board. the pounds per square inch would be the differant from board to the other but the total weight would be the same.. ( I THINK I SAID THAT RIGHT IVE HAD A FEW RUM AND COKES AND ITS 130 AM and im no enginere either.LOL)
