My T3 SS 300WM shot like crap with multiple different loads and shot so so with a couple loads(~1.5" at 100). 180NPTs, 180NBTS, 180NABs, 165NBTs, 150NABs, and I'm sure a few others just never came close to the claimed MOA gtty. I was a bit let down with it then tried a couple 168TTSX handloads with R22 and IMR7828 as well as a box of factory Barnes Vortx 180TTSXs, one of the few times I've seen a rifle make a dramatic change in accuracy. My last 3 consecutive groups with it and TTSXs were 168TTSX/7828 .4, 168TTSX/R22 .4, and Vortx 180TTSX .6 at 100. Dang thing shoots those pills great. Hopefully yours will come around.
Good luck,
loder
