I just installed a Shilen S7 varmint contour barrel (308) on my Savage model 11 this last weekend. I used a go-gauge to set my headspace before torquing the barrel nut and the bolt closed w/o any problem. I then put a small piece of masking tape on the bottom of the go-gauge and was not able to close the bolt, then remove the tape and again tried the go-gauge and the bolt closed fine. I went to range to perform the barrel break in procedure and I was shooting some 150gn American Eagle 308WIN factory rounds and I noticed that the bolt closed a little more snugly than it did before my barrel swap with this ammo. When I later started shooting some of my handloads that I had full length resized and trimmed to length, I noticed that they chambered much more easily and felt like what I thought they should feel like. Do you guys feel my headspace is too tight knowing what I've told you? Do you think that Savage just was a little liberal with there headspacing to accommodate various manufacturers ammo?
