Well Known Nuisance
Winchester xpr, built by Browning.You didn't mention who the manufacture is ? 1-12 T ? tells me that it isn't a standard "monkey see, monkey do" one size fits all US made rifle.
Can't speak for what the manufacture used to "proof test" or test fire a few rounds through your weapon.
Who the manufacture is should tell you the quality of the barrel you have.
As others have stated, and from your posts this weapon will be a hunting rifle so a record of shots from a cold clean,clean bore, and a cold 1 shot fouled barrel will tell you which to go.
