I bought a 112 Magnum Target, the single-shot 338LM model with the laminate stock, assuming it would be as accurate as the half-dozen or so other Savage rifles I have. But alas, it will barely hit the broad side of a barn. In other words, I'm lucky to hit a 16" x 16" paper target at 100 yards. This is Not Good.

I upgraded the muzzle brake to an APA Fat B*, bought an alluminum chassis, bedded the action into the chassis, set it up with an Atlas 5H bipod, Nightforce ATACR on top in a Spuhr mount, meticulously worked up handloads with high BC bullets and low S.D. muzzle velocities ... it's all been a giant waste of time and money.

Other than swapping the barrel for something custom, what can I do to get lemonade from this lemon? Why would a single-shot target action act this way?

And while powerful calibers like this can promote flinching, I shot some rough groups (or attempted to) in basically a free recoil setup with the bipod and a rear bag and me only touching the trigger.
