'Used' - I imagine the majority of deer rifles for e.g. are used 8 months a year, or more - but in the majority of cases (i.e. recreational stalkers) are probably only fired a handful of times. Kirby Allen's 6/338 would probably last a lot of stalkers a life time!
What's your barrels round count to date out of interest? If yours is doing well it must be a good bit of steel, assume youre using Reloader17/RS60 from your notes; the throat and first few inches of my 6XC barrel looked wasted after <1k warm-ish rounds with RS60, still shoots good enough for its intended use, but would win any BR comps 😂
