I wouldn,t want any gun with excessive headspace,even if my insurance was paid up! Rebel hog and others defined it very precise.One other factor comes into play ,and have seen it before.As all reamers are different,thus all chambers are different.Sometimes,through different manufactors the Headspace gauges can have fifferent dim..,thus will give a false reading.Not very often but if 4 guns from Rem or whom every are this way in the same shop,its a real bad bo bo by the quality control people or his headspace gauges may be off. vangunsmith
Hey van, do you think that Remington trys to streatch the life of a reamer? Or do you think they rough ream thechamber, and then cut the threads back to accomdate this? Reason I ask, my friend had a remington 1187 shotgun that wouldn't extract very well. It turns out the chamber was too tight. So our gunsmith said probably remingtons's chamber reamer was wore out, and if you get a shotgun barrel when the reamer is new, you will have a looser than expect chamber, but at the end of its life, a tighter?
Now maybe full of it, but his idea made sense to me.
I watched a video of them cutting chambers with carbide reamers and they cut them so quick, it was amazing and full automated, I was shocked how good the tolerances was.
