SNC4-8001 #1 Sinclair Primer Pocket Uniformers, Small Rifle/PistolSmall Primer Pocket Uniformer Only 09/11/2017
Brewer Bill says, "I was doing the hated primer pocket uniforming with a new tool. I just received the Sinclair Primer Pocket Uniformer, and WOW, this thing is great!
I've used the Hornady and Lyman ones, and compared to the Sinclair model, those are primer pocket uniformers in name only. The Sinclair is a bit on the pricy side, 30 bucks, but it is a superior performer. When finished, the primer pockets look milled-out.
The process I settled on with all brands of primer pocket uniformers is to use them in a cordless drill. I tried using my drill press, but it's too torquey, if that's even a word. Also, using the cordless drill, I have a better view and feel for what the brass is doing. The Sinclair version is milled from a single piece of tungsten carbide and isn't adjustable, depth wise.
When I tried the Sinclair (Brownell's) uniformer, I couldn't believe the quality of the "cut" and the amount of shavings from the primer pocket...very impressive. When I noted the ease and quality of the cut, I decided to re-uniform some brass that I had previously processed using the Hornady and Lyman tools. Holy schnikes! The Sinclair tool ran circles around the other two. Money well spent.
I'm not a competitive or benchrest shooter, I only uniform the primer pockets because I've found the uniformed primer pockets cycle through my Dillon 550 progressive press more consistently."
Makes primer pockets great again. 20/02/2017
Really, it makes a primer pocket great. Most factory brass isn't all too level in the primer pocket and your seating depths will vary without changing the primer pocket itself. Using this tool on vintage rifle cases like 303 British, to modern 6.5 Creedmoor I can achieve a flat, uniform surface in the primer pocket that allows consistent seating depths for primers. An added bonus is that the cutter fits fine in the chucks of a cordless drill, or the handy Sinclair hand-tool specifically made for Sinclair primer pocket uniformers. The cutting depth I've found it to make is 0.130" measured on some 6.5 Creedmoor brass. Pretty consistent to within a thousandth.
