I was thinking about getting myself a set of headspace gauges for .303 but find that Arrowmark is quite expensive and many others don't recommend Brownells because they are SAAMI specs.

I was wondering if anyone here has bought the OKIE headspace gauges. They are alot more affordable (3 piece set for 55$) and are made to mil specs.

What do you all think?
 
If this is the gent from the states who is on surplusrifleforum I wouldn't hesitate. The gent has sold many to forum members there and I can't seemto find a complaint about them.

Most reasonable price is member Gairlochian, he'll sell you a .303 Field mil spec gauge for a reasonable fee and it's Canadian made.
 
I bought a set from OKIE and the no-go gauge was actually a SAAMI spec. After a quick email I had a mil-spec one in the mail, free of charge. You might want to specify the sizes you want.
 
According to Cdn Army EMEIs there were 3 different headspace gauges as follows;

.064 - minimum or "go" dimension
.074 - maximum or "no-go" dimension
.070 - maximum or "no-go" dimension for base/depot repairs

For reloading the aim is to maximize case life. Brass thins and fatigues as a result of repetitive expansion on firing and reduction as a result of re-sizing. This is why a lot of people choose to neck size, rather than FL re-size, for the .303. With neck sizing the case shoulder and case length are not reduced, only the dimension of the neck. This, plus the use of the heaviest brass available, is conducive to longer case life and, as a bonus, better accuracy.

I've owned and used a set of the military go/no-go gauges for years, but some time ago procured a SAMMI "no-go" gauge which measures .067. I re-set all my headspace using this gauge in order to minimize brass flow on initial firing. Heavier brass is always better with the .303 as there is more brass there to thin out on initial firing.
