BURSTFIRE PRIMER POCKET GO GAUGE L & S 2 PC SET

Burstfire - Primer Pocket Gauge Set 

GO GAUGES:

• Never guess again if your primer pockets were properly reamed or swaged.  
• Include large & small primer pocket gauge. 
• Enlarged body, curved (go gauge) / Swirl (no-go) design for a secure grip to be held by hand.
• It can also be attached to an existing industry standard 8/32 threaded hand tool handle, to maximize comfort.
• We all want a tight primer pocket, that will not loosen up before our brass fails. Especially if you use expensive brass.
• Using small primer pocket as an example. Our small gauge is made to 0.1725. Variation for small primers is 0.1745 - 0.1755 in diameter. ***Majority of small primers will be 0.175.
• Burstfire has found, a .175 primer, can be inserted in a .1725 pocket on a press, but may meet some resistance at .1755 (Will not work in most cases if hand priming. In this case simply set up the reamer / Swager to go just a tad bit further). 
• ***Proper use of gauge: Make sure the gauge can be freely inserted into the pocket, without sticking / without requiring any force to push it all the way in or pull all the way out. 

If you want the highest level of precision and control, this is it. But keep in mind there are variations from brand to brand, and lot to lot. Cup thickness is a factor in if it will fit or how easily it will fit as well.
