SINCLAIR FLASHHOLE REAMER Reviews & Ratings

SINCLAIR FLASH HOLE REAMER

These tools are designed to ream flash holes to specific diameters rather than debur. The handloader addresses three issues when using this tool. 1) It enlarges the holes just enough for the die maker's decapping pins to go through without getting stuck. 2) It removes any burrs left in the flash hole during manufacturing. 3) Each flash hole will be exactly the same size ensuring uniform ignition. This three-piece tools have a stainless steel guide that centers the reamer in the primer pocket, a knurled stainless steel handle and either a .0625” or .081” reamer for small or standard flash holes.

A must have for Lapua brass

I use this to square up all my 6mm BR Lapua brass primer pocket flash holes.

Easy and Uniform

I am using this on new Lapua 6mm BR Norma brass. These cases use a small primer flash hole. The hole varies from about .059" to about .063". A quick twist with this tool makes each case about .063" or just under. Having every case nearly the same certainly can't hurt accuracy when your trying to gain every little advantage you can. Also a small decapping pin is .0625" and a person can use a decapping die (with the small pin) after reaming the cases with this tool.

Worked perfectly

Received reamer and used it on 250 cases initially without a flaw, worked perfectly. Additionally, it make evident several cases in which the primer pockets were not straight. I checked and my gun screwdriver set had an Allen key that fit perfectly should it ever need to be taken apart.

Quality, precision

The small decapping pins fit tight in the 6BR Lapua brass flash holes and sometimes pull the pin out of the decapping die. This precision tool opens up the flash hole slightly keeping it square to the primer pocket. This should solve the problem.
