Hi all!
Having a few conversations on other forums about head space in a .260 Savage I just built. There is a lot of conjecture, plenty of guys saying "just buy the Go Gauges" and others who think my logic is flawed.
As I am new to the headspace game I thought I'd ask you all since this in my experience is the most knowledgeable group of reloaders in the internet.
So to start: SAAMI minimum head space for the .260 is 1.630. Maximum is 1.640. That much I know. And as a reloader exclusively, and never intending to shoot factory ammo in this gun, I suppose I really don't care!
Instead, using my Hornady headspace bushings, I properly measured a piece of 7MM-08 brass that I resized down to .260 from the head stamp to the datum line (for the uninitiated, the tools are BUILT to do this).
My brass, sized by my dies sized down to 1.620. I then headspaced my Savage build to this piece of brass, making it so I have slight tension while closing the bolt.
2 pieces of tape on the end of the brass makes it 1.625. Again, measurements made using the bushings and my micrometer. The bolt BARELY closes with force on this piece of brass.
In my mind, I made my own go and no-go gauges. As I plan on always FL resizing my brass using those dies, and will NEVER use factory ammo, I think I am good to go.
Seem reasonable?
