I bought the Hornady headspace gauges and I'm seeking confirmation that I'm doing this right. After installing on my caliper and zeroing it I measured a fired 7mm RSAUM case and came up with 3.630. This case was fired in a Remington 700 titanium. Anyone else here shoot this caliber and if so, is that a reasonable measurement for a fired case? I'm just getting serious into this headspacing thing. I used to set my sizing dies to the manufacturers specs, but am looking to improve my groups a little.

| funny lookin headspace gauge to me.guess i dont keep up on the latest gadjets.if you want to get the best accuracy quit buying all that latest goo-gaw and keep it simple.neck size,trim and burr cases,pick a good lookin load from the book and go to work.play with powder weights and seating depth.aint no magic doo dad that you can set to factory and get instant tack drivin results.every combo is different.now i know we will hear from the GADJET GURU's.

| Good idea. I can't be sure your numbers are correct. The key is to measure fired vs. sized rounds. Sized rounds should measure .002 - .003 under your fired rounds. That is easier said than done consistently. Consistency will depend on your ability to lube for consistent sizing effort.

Hey Wheeez,
I understand your point. I've done that for years. Picked a load from a manual and "worked" with it until I got what I was looking for. Somehow I got wrapped up in this gadget phase and am trying to work it out. I may just have to follow your advice and go back to the old way of doing things. Thanks for the advice.

| Headspace gages, neck mics, runout gages, etc are proven ways to get to safe, accurate, and reliable loads quicker. If you want to do it do it by the guess and check method, reasonably good loads can result from that too.

The Hornady (Stoney Point) tool is a comparator. You use it to compare with something of known value such as a new case or a resized case versus a new case.
I have one, Stoney Point, and have found it very useful. As an example I found that my M1A had 0.002" head space while my 40X target rifle had 0.006". This was very suprising to me as M1As are notorious for having long headspace and the 40X is a gun out of Remingtons custom shop. So the M1A has perfect head space while the 40X is exceedingly long.
I highly recommend getting a set of the Reddidng incremented shell holders. I use the 0.004" shell holder for the M1A and the 0.008" for the 40X. That way I can presicely move the shoulder back 0.002" every time.
