Hey guys. I've been having a difficult time trying to figure out why I am getting such terrible grouping with my Weatherby Accumark 338-378. At 100 yards, the accuracy is all over the place, and i'm talking 8" at times. The scope I am running is a Leupold VX-3L 4.5-14x50. I am shooting from a solid table, with the gun in a fairly heavily weighted down rest. I was grouping very well with my old Weatherby 300 mag in the same rest. Do you guys have any ideas for me? Whitetail season is fast approaching, and I'm running out of ideas. Here is the load specs: 20 brand new brass, and 20 once fired brass 180 grain Nosler Accubond Spitzers 110.0 grains of IMR-7828 Federal matched 215 primers 3.763" total length I wanted to eliminate as much as I could, so I picked up a new box of 180gr bullets, a new tin of 7828, and a new box of matched primers. I yanked the stock off the rifle to ensure there was no barrel floating issues, and everything is perfect, as I expected it to be.
