[QUOTE="Takem406, post: 1078948, member: 72588"] Found some boxes of Grandpa's 270 Weatherby loads. The boxes are marked 72 grains of 4831 (doesn't state IMR or H) and 150 gr Partition. I checked the Nosler and H/IMR data and the max loads are around 68 grains for that powder. These were probably loaded about 35+ years ago. Did the older powders run a lower pressure? He obviously shot several of these loads. There's about 50 of them. Also he left me with several boxes of old CCI mag primers. Has CCI changed in the past 40 years? I know they will still go bang, but will they be as accurate and consistent as new ones? [/QUOTE]
