Well, after weeks of searching forums, endless load testing, and a good percentage of my barrel life gone, I have come to the conclusion that the last two lots of 7mm 150gr ABLR's were flawed from the factory. Back story- I was gifted a Cooper m52 in 7STW for Xmas by my lovely wife. It's my 3rd rifle in that chambering, so I decided to try something different than my standard SMK loads. After reading about Accubond LR's high BC, I decided to give them a whirl. After little load testing, I came up with a load that was shooting .2's and .3's consistently @ 3315 fps. Fast forward through 100+ bullets and about 50 deer and hogs, and I notice several POI variations from my aim point on animals. After checking at the range, I realize something is haywire. I bought a second lot of bullets, and I am struggling to keep 5 shots on paper at 300 yds. I have a very strict break-in and cleaning regiment, so I know that's not the issue. I change optics, I rebed, I whiddle out areas of concern in the stock. All to no avail. So I try some 130SMK's I have loaded for one of my other rifles, and quickly shoot a 1/2MOA group at 300. I try some 168SMK's and shoot a .290" OUTSIDE group at 200. So I contact Mike Seay of Nosler with my issue, and he basically says "that's weird". I noted variations in 10 randomly selected bullets of 0.5 grains weight and 0.050" in bearing surface. He seemed to think that was "within specs" and offered no help. I have tried H4831SC, H1000, Retumbo, and Norma MRP, in 1/2 grain increments up and down, and the best it will do is 3.5" at 300. I have read several other threads about people not being able to get the desired accuracy, or any accuracy, out of these bullets. I am thinking it depends on which box you get. Needless to say, I am done with Nosler!
