Osky,
Not being a dick, but it’s pretty well known the Bmag is junk. Savage did a nice job on their model 93R’s in 17 HMR. The Bmag was a huge miss.
With that said. Most 17 WSM’s will lack the ability to drive consistent knotholes. Ammo could be a contributing factor.
Your situation sounds strange though, I admit.
