 Stoney point told me they didn't have a head space guage for my 7.7 Jap rifle and that ablank would have to be drilled out to make one. Then they sent me an e mail saying their C-375 guage would work as it was made for the 7 x 57 and would work for the Jap as well. I disagree with this as the 7 x 57 has a taper of 20 degrees 45' and the 7.7 a 23 degree. Seems to me the 23 degree angle would never seat properly in a 20 degree guage. As the head space is measured in the middle of the taper it would never seat against the 20 degree taper. Might just be something I am missing on this! | ||

If I were you I would call either Clymer, Forster or Dave Manson if you are looking for head space gauges. Stoney Point makes great walking sticks! | |||

 Why the fixation on that gagae Blob?  rogerOld age is a high price to pay for maturity!!! Some never pay and some pay and never reap the reward. Wisdom comes with age! Sometimes age comes alone.. | |||

You asked why the fixtation on the guage? I thought this was a fourm that you could ask a simple question and get some answers. I was wondering if the 20 degree angle of the guage used for the 7 x 57 would bring about a wrong reading on the 23 degree Jap. This not fixtation just asking a simple question! if you don't know then don't answer as there are enough idiots filling these spaces already! | |||

Hey Roger, Yeeee-Ouch! Looks like you got ripped a new one for asking a simple question.
Well, I for one "know the answer", but at the risk of offending any thin-skin types, I'll just keep it to myself. | |||

I did not know that Stoney Point made headspace gauges. I thought they made seating depth comparators. If you are talking about a comparator then they are probably right, a 7x57 will work. You are not measuring a specific distance with a comparator but only a measurement that can be compared with other measurements. Did I say that right? In order to measure headspace you do need a headspace gauge. Ray Arizona Mountains | |||

http://www.stoneypoint.com/headspace_index.html Guess I never knew there was a guage to measure headspace from fired brass. As usual just my $.02 Paul K | |||

Just because Stoney Point calls it a headspace gauge doesn't make it one. A headspace gauge in the traditional definition is a precision ground gauge to measure a rifle chamber as it is being reamed in order to assure it meets some specification such as SAAMI. What Stoney Point is selling is what most benchrest shooters call a "thingy" or "gizmo" since there is no established name for it as far as I know. It is used to measure shoulder bump. Most BR shooters use one that is much simpler than Stoney Point's, being made from a short section of barrel blank and the reamer that was used to cut the chamber. Like a comparator it does not measure any specific dimension but allows the shooter to compare the shoulder location of fired brass with the shoulder loaction of new fire-formed brass to determine how much shoulder bump is needed to assure smooth chambering.

I was just given an RCBS "Precision Mic" by a friend. That's one of the two uses of the Precision Mic. One is to determine the headspace of a given rifle chamber using an average of measurements from three fired cases, the other is measuring seating depth of bullets to the lands. Works pretty well, once one understands how to use it. Each "Precision Mic" is for a specific cartridge, so there is no really great money savings. And, you can't use one very practically in the process of chambering a rifle. But, if you have a rifle where, for instance, primers are backing out of the cartridges a bit, the "Precision Mic" WILL let you determine what the true headspace of that rifle actually is, to .001" of an inch, and determine from SAAMI specs whether your chamber is in or out of spec. Added by editing: Just for fun I tried it with my Sako Safari-grade .338 Win Mag. It did a great job of measuring the headspace to the datum line on the whoulder of the .338. Turns out my Sako only has .0005" (half a thou) more than minimum headspace. What is even more interesting to me, is that factory loaded 200 gr. power-point ammo, though only a few thou too small in the headspace measured using the convention "belt" measurement, it has MORE than .050" excess headspace when measured to the datum line. Thus, while it is safe to fire, it sure as hell IS sloppy ammo making by the manufacturer. My country gal's just a moonshiner's daughter, but I love her still. | |||

I'm sure the Precision Mic works fine. I just bump the shoulder back a little at a time until I get the "crush" I want then lock the dies in. As usual just my $.02 Paul K | |||

Perhaps he needs to check the headspace on a 7.7mm Jap rifle, perchance?? "Bitte, trinks du nicht das Wasser. Dahin haben die Kuhen gesheissen." | |||

Mr Ramrod340, you need to be careful with that method as you could be feeling the area above the web and not the shoulder.I have seen it many times and the people keep bumping the shoulder back and then you get case separation. You need a guage to be sure. Butch | |||

Oh well fellers it doesn't matter to much as I set the head space with my dies anyway. Jusy wondering about stoney's claim. i am not experiencing any problems just finding out a few things.  | |||

OK I'll bite. For what reason? Is he going out and buy some ammo for this rifle? If he is reloading he adjusts his dies to match the irregular chamber if such is the case. I wasn't being a smart ass . I've followed Blobs same quiry on other threads and it's always back to a gage for which I can not see a benefit. That really was the question what was Blob looking for.What benefit would this give him? Right now Deguello, after adjusting to your simple explanation, I guess I don't really give a big rat's ass.I also am beging to believe that all these Blob 7.7 threads are a lot of  The only thing that holds it all together is the revered status of the 7.7 Arasaka.   rogerOld age is a high price to pay for maturity!!!

The Stoney will measure from the case head to a point on the shoulder. If you measure a full length resized case and then measure a fired case you can tell how much it has expanded. If you have a question about a rifle's headspace, better take it to a competent gunsmith and let him measure it properly. Check the last portion of this Link Oh, Blob1, you're not right. Back to the still. Spelling, I don't need no stinkin spelling The older I get, the better I was. | |||

If I can find my Stoney Point, I will let somebody have it for shipping. It is not that good for setting seating depth with their supplied cases. They are loose in your chamber, so unless you take cases fireformed in your chamber and tap them yourself,you won't get a good reading.Send PM if interested. Butch | |||
