I have a WBY Accumark in 338-378 ,tech problems so far like destroying standard Leupold base and rings( Came with rifle) installed a rail and it revealed I guess factory scope base screws are off,shot 6" to right,with left windage maxed out at 50 yds.(Zeiss V6 ) So waiting on some Burris XTR signature rings with off set shims to fix that problem,then I'll get down to some load development . So also thinking when I burn this bbl up ,inquiring about options.
