I have a WB Vanguard S2 weatherguard in 7-08 that I have spent hours testing loaded and reload round to achieve MOA accuracy and am not finding the results that I should be seeing. I've played with powders, different bullets, seating depths, mono's and cup cores, etc. My question is this, how much work should one invest into a gun that you like before sending it down the road? And would you be tempted to try a different caliber as its replacement?
