Primer pocket uniforming and flash hold deburring tools

BLS700 · August 1, 2008, 12:23 PM

I was searching the internet for a good primer pocket uniforming tool and also a flash hold deburring tool. I found a lot of complaints and very few satisfied customers so I was wondering what companies you all have found to produce quality tools in these fields and where you found them? Did these processes improve accuracy for you? I will be reloading for .308 (primarily) in a Remington 700 SPS-V using (as of right now) Nosler custom brass (which does come flash hole deburred) and CCI primers but I will be trying federal 210M and CCI BR2 primers soon. Thanks for any input you can give.

I use the Lyman tools, but some people will try to expound on the vagaries of Sinclair, Wilson, RCBS etc. I bought mine eons ago before Lyman saw fit to bring out a brass prep combination/case trimmer setup. The primer pocket uniformer is SLOOOW but does a good job. I chuck mine in my Craftsman cordless drill that has 2 speeds; 350 and 1200 RPM, and use the slow speed. You have to go by feel, and it tales awhile if the pockets have a lot of metal to remove. The flash hole tool is a joy to use; I size, trim, deburr and inspect before I uniform to make sure every case is the same so the uniforming makes them as identical as possible. One pass with the drill and they are done forever. I really like the adjustable stop on the tool as it bottoms on a .223 case, and fits inside larger cases when doing them. I also uniform the flash holes BEFORE primer pocket swaging for the same reasons; identical cases.

Another Lyman user here. Yeah, it's a little slower but you only do it once to a piece of brass so it's time well spent IMO. I also check flash holes with a .080 drill from the primer side just to make sure.

Sinclair

I have used a Sinclair flash hole deburrer and a Wilson primer pocket reamer for decades. Had absolutely zero problems with either. They are several other manufacturers of the tools - it's really which one you buy first becomes your favorite.

I prefer to use a RCBS swaging tool, it removes no metal and simply"moves" the brass to the correct size. It works great on military crimped cases.

I use the Lyman tools also. Never a problem

I use a Possum Hollow primer pocket uniformer. It's a hand tool only and the 1/2 hex body won't fit into a 1/2 chuck on a hand drill. It's a good tool though and not expensive. Plus it has large and small cutters.

Sinclair...
• made from solid tungsten carbide
• no set-screws to mess with
• can be chucked in a ½" drill

I've used the Lyman Flash Hole Deburring tool for many years. Since I have never used any other, I have no way to compare it with others, but I am well satisfied with it.

In 48 years of reloading, I have found that cleaning primer pockets is a waste of time. When fixing the military crimp on primer pockets, I find a swage tool to be much more effective than a reamer.

As suggested above, all of the tools commonly available do good work when used correctly. Most often the complaints about a tool are from a lack of understanding or misuse, not a tool defect.
