[QUOTE="entoptics, post: 2561174, member: 104268"] Couple more things to note... MAP is 65,000 PSI for 7 PRC and 61,000 PSI for 7 Rem Mag. 5% greater pressure. I calculated external case volume from the drawings. 7 Rem Mag, not including the belt, is only 2% larger than the 7 PRC. I think we can blame Tikka for the 3.34 OAL. Their long action boxes are about 3.37". I believe the next shortest "Long Action" factory standard box is on Savage rifles, and that's right at 3.5". If it weren't for the popularity of Tikka, Hornady could have gone to 3.45" for another couple grains of H2O capacity... Stupid Tikka and their accurate and economical rifles...;) Regardless, if interior volume scales to exterior volume, I think this will meet or exceed 7 Rem Mag, and do so with a 1:8 twist. That's a good thing for "off the shelf" shooters. [/QUOTE]
