I’m in the planning stages of my first barrel replacement on a factory 700 adl stainless synthetic in 300 wm. The factory sporter barrel has about 80 rounds down it and really likes the old black and red box solid base Nosler 180’s. Accuracy is not the issue but the recoil has always been unpleasant. I’m leaning toward a threaded carbon barrel with a brake to keep the weight down and reduce recoil. I need to understand the custom chambering options. With the current questionable availability of bullets, how do you select one to base your chamber specs on? The “what if’s” have me at a standstill. If I spec out a chamber for weight, OAL, throat, freebore etc. of a particular bullet and then find out the accuracy is unacceptable or the bullets are unavailable , where do you go from there? What if I chose a twist rate to shoot the heavies but decide at some point to shoot some lighter bullets, will accuracy still be acceptable? I want to make an informed decision and understand the risks and rewards of these choices. Any help would be appreciated.
