Tittle gives you the rundown. Years ago, I bought a Savage Hog 308; it has a 20” medium weight threaded barrel. It was my first and will be my last Savage. At the time, it was one of the only affordable factory guns with a threaded barrel, which is why I bought it. It has never been a good shooting gun with anything I’ve put in it from FGMM 168 to a variety of hand loads not to mention that my RCBS X die will barely push the shoulder back far enough for a reload to chamber in it; my Hornady die will not. It’s also always been the most difficult to clean of any I’ve owned. About a year ago, I bought a bore scope and discovered why. Here are three different photos of three different spots in the barrel.
