[QUOTE="Shortmagman, post: 1051379, member: 10723"] When it is too cold to shoot or you think it is too cold you can come up with some different things to do. I have loaded for my Remington CDL in 280 Rem for sometime. During that time I have used brass made by different companies. It was not too long ago that I noticed that I seemed to get pressure signs earlier when I used Nosler brass. I decided to see if I could determine the difference in volume between Nolser, Remington, and Norma brass. I know that what I found is not the final answer since my sample size is so small, but it did prove to me what we have always heard-when you change brass you need to start over and work up. Here is what I did and what I found. I checked the volume of the cases by using H414. I filled the cases to the top, and then I weighed the H414. I did this for three different case from the same lot with a spent primer in the pocket. This is how much H414 each case held in grains. Nosler case one case two case three Average 68.6 66.4 67.5 67.5 Norma 70.7 71.2 70.3 70.8 Rem 69.9 69.5 68.2 69.2 It was very clear that the Nosler case was smaller in volume. I then weighed the case without the spent primer to see what I could fine.This is their weight in grains. Nosler case one case two case three Average 199.6 200.0 199.8 199.8 Norma 181.7 181.9 181.4 181.6 Rem 195.5 195.3 195.3 196.36 What I found was quite interesting. We have all been asked why weigh your cases. The answer has been that the heavier case have less volume. My little experiment seems to show that. I think it does prove that when you change cases start over and work the load up. [/QUOTE]
