Lyman hand tool which can be used in cordless driver or drill.
It was found while deburring flash holes. I still uniform flash holes.I've seen no flash holes three times. All same caliber, same make, same lot. It was recalled. Speer made Browning marked.
It is a different kind of 'blow up' that really gets attention and usually ruins the bolt face.
Hi all quick question : dose flash hole deburring make any difference to accuracy ,only advantage i see is in large case with a magnum primer in very cold conditions to help with a clean burn...........
You will be, if you do this. Go back to my #13 Post and click on the thumbnail of the cutaway cases and click on it. It will open on another page enlarged. At the top rightish of that page you will see a small magnifying glass symbol with a plus sign (+) in it. Click on that and it will give a slightly larger 'zoom' view, and you will clearly see that the burr height is uneven around the circumference, as I explained in my post #19 above.Sadly
I cant zoom on your image.
Jack, the only caveat I will add is that since Warren Page's BR days a lot has changed. While he was certainly one of the 'Fathers' of modern Benchrest, the later BR crowd has, through experimentation in all areas of the sport (case prep. being a part of that), has advanced the sport a whole bunch, with group size 'telling the tale'. I'm betting the miniscule groups regularly showing up in todays match reports are not a result of 'Global Warming'. I think the mantra of the BR guys might be "While this (whatever it may be they do) may not help....it certainly can't hurt!".As mentioned above, Warren Page was a first page BR shooter and went a season without uniforming, deburring or cleaning his primers and 'lost the same number of matches'.
Good choice, that's the one I have been using for about 35 years, as shown in #13 above, you'll like it.its a KM FLASH HOLE UNIFORMER n
Not a stupid question. The .080" hole has been the 'standard' for many years. The .062" hole is primarily found in the Benchrest (and long range) type brass, depending (a little bit at least) on the manufacturer (Lapua?), and yes, PPC, 6 BR, 6.5 Lapua, some 308 (Lapua Palma match brass). Some feel the small hole 'concentrates' the primer flame better to improve consistency of ignition, though some have experienced problems in cold weather with the small hole.Ok might be a stupid question but what cals dose the smaller one do PPC .062" ??
