a friend of mine made a mistake the other day. the scenario was grabbing the wrong powder to load his 300 win mag.
standard load was 78 gr ramshot mag under a 210 berger vld, with fed gm215m seated to .005 into lands.
everything went south when a charge of 78 gr of win 760 was used. to say it was violent would be an understatement. case was ruined, chamber has a bulge in it, sako extractor doesn't look the same anymore either. we are just happy that the nesika held the pressure and he is just looking to clean up the chamber with an ultra reamer instead of visiting him in the hospital.
so the question is...what kind of pressure was that load running. the 210 did hit the target, just got there with 24" less drop @ 660 yards. i took a wag that was probably running around 3300-3400fps instead of the normal 2860.
any insight would be appreciated. thanks again
