[QUOTE="SpikeSniper, post: 1098070, member: 29703"] 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.
