[QUOTE="tankgijohn72, post: 1325092, member: 77441"] Doubt your change in pressure has much to do with the atmospheric pressure. The round is essentially a closed system when fired and not really exposed to the pressure change, with the exception of the bullet. Would be interesting to test in a controlled environment. Would say that new brass is the likely cause. Brass, even from the same manufacturer can vary in hardness. Ambient temperature, bore condition etc are other things to take a look at. [/QUOTE]
