You might take note as to why, I suspect, Jerry does that.
The 2500’s are about the only threaded action made with tolerances so close you can reliably swap barrels between them, i.e. action specific.
That said, with different approaches to tighten the barrel, the fit is fine but the extractor slots may not match up perfectly every time, especially if cut close, thus the milled breach, eliminating the issue…..kind of an exception to the “ rule” if you will.
Barrels done properly, with proper slots, in my experience, don’t get misaligned, but guys that swap barrels use anything from “ snap tight” to 100lb’s+ so slots can get tighter than ideal.
I’m with TKH. I want that barrel to butt up tight to the action face. If I want to swap barrels it’s with another fit to that action.
