[QUOTE="wonderman4, post: 2338161, member: 72101"] I was fortunate enough to have bought all my brass back before Hornady, Nosler, and others began making the stuff. I would say back in the 60s and early 70s. BUT, that does not mean the brands that I have (Winchester, Remington (includes R-P) and Federal) were anywhere close to being the same. For example: My mainstay was Winchester brass. I would have to drop charges approximately 3 grains to prevent any high pressure events when using Remington brass in the 30-06. Federal was close to the Winchester Brass so no adjustments were necessary between the two. As others have previously mentioned, it is prudent and very wise to drop charges to prevent any incidents. How much depends on the rifle and the load and the brass. The old rule of 10% is a very good one. Weighing brass cases is not a problem, but I would suggest to also measure water capacity. Put a drop of dish soap in a half cup of water to break the interfacial tension of the water and it is a piece of cake. I did this back then and would do it again if I was starting with a fresh batch of new (or once fired) brass. How else are you to know?? [/QUOTE]
