Hello All,
Just got my Clymer Field gauge [.308] to do some headspace checking on a couple of rifles.
The first one I want to check is a Mauser 98 action, chambered in 7.62x51.
I realize that the numbers indicate a .308 FIELD gauge is actually about the same as a 7.62x51 NoGo gauge. However, I have a few .308 lever/semi's to check later- so wanted one tool for all. The others are Garand [yes, in 7.62x51], Saiga 7.62x51 and Savage 99F in .308.
Two questions.
Does the Mauser extractor HAVE to be removed to use the Clymer Headspace gauge?
I notice the Clymer HS Gauge has a rim cut in it for the extractor, and was able to slide the gauge up under the extractor rim.
I was able to use it, UNDER the extractor claw [i.o.w., with extractor holding it to the face of bolt], and the straight bolt went in and pivoted from 12 oclock [up] to between 1 and 2 oclock [or 45 degrees down], before it stopped. I didn't FORCE it, but brought it to where moderate resistance was felt.
The second question is about how many degrees of an arc does the bolt handle make between a NoGo and a Field Gauge [between about 1.635 and 1.638"]?
Would the amount of rotation in the 'lock up', indicate that the NoGo would go into chamber, but the lugs would not begin to engage [45 degrees of rotation difference between them], or is the difference between a NoGo and Field more likely to get the straight bolt handle to point from 12 to 1 oclock [about 15 degrees difference between gauges].
I am hoping I don't need to remove the extractor, but will do so IF I HAVE TO.
Any tips on what to expect?
Again, this is a Spanish FR8, which is a 1943 Spanish Mauser, that is basically a K98, which was rebarreled [with a Cetme front sight post/bayonet lug/flash hider] into 7.62x51 around 1955. Functionally, it is a Mauser, even if it technically isn't.
thanks in advance!
