[QUOTE="Brent, post: 23757, member: 99"] Well I have good news, but I can't explain it though. The cases I weighed spanned 4 grains. If you go back and read my previous post I said the cases with water spanned 4 grains also. I looked at it totally *** backwards, probably because I expected the results to be what everyone might think, all the lighter cases would have more internal capacity, right? Wrong.. the cases that were 4 grains lighter were still 4 grains lighter with water, meaning that internal capacity was EXACTLY equal! Each case was lighter by the same amount with water as the case weight itself indicated. Am I making sense? It wasn't the other way around. The average water weight itself was 115.7gr. Maybe some of you guys can check yours too and see how consistant accross the board this 300 ultra brass is. Mine was filled to the top with water in an eye dropper with a drop of dish soap mixed in to break the surface tension, no bubble on top, just flush with the mouth. They fireformed once and had fired primers in them at 2.840". Boyd, this explains why you find no difference at 1000 yards. And we all frowned on the Remington brass. I am totally amazed to say the least. I might add that this was two boxes of brass from different lots too! This may be an end to my weighing cases if this proves to be true the next few times I check some. These cases were all within +or- 3 tenths of a grain in internal capacity on cases that had a 4gr spread, WOW! I thought you all would appreciate hearing this. [/QUOTE]
