[QUOTE="MagnumManiac, post: 2817977, member: 10755"] Brisance, a fancy name for heat, is the main concern when talking primers, but in recent times, it has become widely known that a SRP used in a case as a replacement to LRP increases case life and does improve ES/SD numbers as the smaller flash hole in conjunction with the gained surface area within the case, pressurise the case differently by increasing start pressure. The 6.5x47 and all the PPC based cartridges have proven this, including the BR, BRA and others. In other words, you have stable brass right from the get-go that doesn’t change as much as does LRP brass in the same case head size. Cheers. [/QUOTE]
