[QUOTE="shogi, post: 2056453, member: 18596"] Bought 6 boxes of Norma 308 Norma mag 180 gr Oryx precision ammo from Trade Ex Canada (T.E.C.) and all were from the same lot. I had purchased a Browning Safari grade 1 along with a Sig Sauer BDX scope/rangefinder and had planned on using the combo on a bison hunt this last fall. After putting the rig together, I attempted to zero the scope and noticed very quickly that there was vertical stringing despite not changing the aiming point. Set up my chronograph and found the FPS was ranging from 2366 to 2896 (Norma states that FPS should be 2960) and everything in between. I contacted TEC and they informed me it was Norma’s issue and after contacting Norma they replied that the cartridges were loaded correctly and that it was a transportation issue. I was considering just pulling the bullets and weighing each charge but decided to weigh each cartridge before doing that. The total weights ranged from 478 to 483 gr with the majority in the 481-482gr zone. I’m thinking Norma is right and they were damaged in transport or stored incorrectly due to weights being somewhat consistant. Should I pull the bullets and weigh each charge or should I just forget it and accept the fact I just ended up with some really expensive brass? Options? Thoughts? [/QUOTE]
