[QUOTE="J E Custom, post: 1113854, member: 2736"] A few more comments about a 7/08 AI. First, If you are re barreling or building from scratch the 7/08 AI would be a good choice over the standard 7/08 because not only would it up the velocity, the brass will last longer because of the 40o shoulder and the added case capacity will allow you to use other/slower powders. There is an efficiency advantage in the AI cases (Less powder to get more velocity) and many bench rest shooters believe that the 35o to 40o shoulder is more accurate. It is also a good way to clean up a poor 7/08 chamber when you set the barrel shoulder back 1 thread you clean up the lead angle and the throat. and no modifications to your receiver would be necessary. Some feel that feeding becomes a problem but I have never had a feeding problem with the 40o shoulder. I don't look for velocity gain when I go to an AI cartridge, I look for total performance in the size of certain cartridges. There are many cartridges that are faster than the 7/08 or the 7/08 AI so it becomes a choice of performance and recoil as to which cartridge is best for you. J E CUSTOM [/QUOTE]
