[QUOTE="baldhunter, post: 2628685, member: 11853"] What is your OAL length?I still say SAAMI specs for the 300 Win Mag is way off.The OAL length of 3.340 is way too short.The 300 Win Mags I have are around 3.550 to the lands.To give you and example as to why I think this is an error,take a look at the case length of the 300 Win Mag and the 308 Norma Mag.The Winchester case is 2.620 and the Norma case is 2.559.OAL for the Winchester is 3.340 and the OAL for the Norma is 3.347.I ran into an issue with a Sako A7 300 Win Mag.It is built on their M action and the rifle magazine is too short for this cartridge to feed and shoot accurately because I would have to load the cartridge under 3.300 for it to feed in the magazine.In doing so,the short neck Winchester case is already getting on the bullet ogive and with so little neck tension on the bullet,I could push the bullet in by hand.The rifle shot like crap with deeply seated bullets,around 1.5-2.0".I had some ammo loaded for another 300 Win Mag with a long mag box.The OAL is 3.490.I tried it in the Sako and shot this group.The Sako was 3.550 to the lands,so that was a .060 bullet jump.So now I will just have to shoot it as a single shot.You only need one well placed shot with a 300 Win Mag anyway.
