This is my first barrel swap and I finally got my new McGowen 338 Federal barrel to finish the build. I screwed the barrel on until it just touched my Pacific Tool "go" gauge and locked down the barrel. I then put one piece of clear tape on the go gauge and and it still closed the same as without the tape. I put on a second piece of tape and the bolt would not even start to cam over. I measured the length of the gauge as follows.
No tape 1.9245
One piece 1.9265
Two pieces 1.9285
I did this four consecutive times and came up with the exact measurements every time. So it looks like I have somewhere between .002 to .003 headspace. Do'es this sound good? Just wanted to ask the experts before I test fire.
Thanks!
