Hello, I live in Modesto, and am going to be getting my first 91/30 to start the addiction. I have heard it's a smart move to check the headspace and I could get a set of gauges, but I am thinking that maybe it would be wiser to have a gunsmith check it out. Firstly, should I do it myself with a set of gauges and spend the $54, or should I have a gunsmith check it out? Secondly, who is recommended and what do they usually charge for a check? I don't mind driving a bit and I'd rather be on the side of caution before I rest my cheek on the rifle and hope the bolt doesn't blow out the back. Thank you in advance.
