[QUOTE="308win, post: 3062772, member: 102230"] No. It doesn't matter if it's a standard 7-08 or an improved 7-08AI, the max pressure is 49,900CUP. The 300WM was certified at 54,000CUP does not apply to your cartridge. With the basic information given, Quickload is showing you to be slightly over max pressure. Understand that Quickload does not use CUP in its method, but Piezo. It states that "CUP units cannot be converted into piezoelectric pressure units that are useful in Quickload data". Regardless, the Piezo Pmax is 60191psi and your load is generating 60935psi. In my opinion I would not go above 48gr H4350, but look for a powder charge at a lower capacity. I'd you are into Optimal Barrel Timing (I've found this to be very useful for initial load development) then you need to be working around 47.2gr and 2763fps. This drops your pressure to 57884psi. Again, this is all a guess using Quickload, but will get you fairly close. I also shoot a 7-08AI and would caution you when looking for pressure. AI cartridges tend to hide pressure until you get WAY up there!!! Good luck with your process, proceed with caution [/QUOTE]
