[QUOTE="magna19, post: 3210934, member: 24646"] Ive read that some of the older writers measured the expansion ring to determine maximum pressure. Also some of these firearms were re-barreled during load development from bulged chambers to soft barrels etc.. I suspect a lot of brass never went more than 2 firings also. I use the Bob Hagel data for comparison to the more modern data available today. If I see any modern data close to his I pay more attention to near max data. I pay very close attention to brass case capacity, powder lot, primer, temperature, freebore, and usually keep barrel clean every 5-10 rounds when working with any loads near his max listed. The only way to see if you have cartridge that will produce his claimed velocities is to try and approach them. I do have a 7 rem mag that gets all his claimed velocity with a 150 Nosler Ballistic Tip and a Berger 168 Classic Hunter that he would be proud of. [/QUOTE]
