My nephew said a gunsmith friend of his put him on to tuning the rifle to the load with chamber bedding that is cut back until it shoots good. Anyway, my nephew developed a load for his 338 Edge that had good velocity without pressure signs. He didn’t worry about accuracy other than to note what it was. The load shot 1.5 inches at 100 yards. Then he cut back the bedding ¼ inch and went back to the range. With the exact same load he is now getting ragged holes at 100 yards. Per the gunsmith you are then supposed to do some minor tweaking of the load to really tighten it up. The gunsmith has the best of his rifles shooting 0.3” ten shot groups at 200 yards with this tuning method. I was always told to float the barrel which means you don’t bed the chamber part of the barrel. But I’ve seen the targets and they are pretty compelling. I may have to give this a try but before I do I thought I’d ask if this is general knowledge and I just didn’t get the memo. Any of you guys that do some tweaking already doing this? Any thoughts?
