[QUOTE="davkrat, post: 1065428, member: 6452"] I have ran in to the same issue with 7mm Rem Mag. On the Hodgdon data page you will see for H4831 and a 150 grain Nosler Partition the max is 62.0 grains at 2,986 fps while the same powder behind a 150 grain Barnes TTSX is 68.0 grains at 3,080 fps. You don't usually hear that you can increase the powder charge when switching from a cup and core to a copper solid! The 7 Mag data is always complained about for being limited. I have read numerous times that the cartridge should have been set at a higher SAMI max pressure. The .308 Win is "allowed" to be pushed to a higher pressure yet I shoot both out of nearly identical Remington 700's. Basically you may end up treating the 7mm Rem Mag as a wildcat. Play it safe and listen to what the brass and your chronograph are telling you. That's what I do. I've settled on a load that is not hard on my brass and gives me good velocity. It falls somewhere within one of the books ranges but other manuals I am significantly over max. All the other cartridges I load for seem to be very similar when compare between manuals, the Big 7.... all over the place. [/QUOTE]
