Oly Posted May 20, 2009 Report Share Posted May 20, 2009 As many decent primer pocket uniformers are depth adjustable I was just wondering to what depth are people uniforming their primer pockets for .243Win? Do you alter this for different cases/primers? And if so how do you determine the correct depth? Thanks in advance, Oly Link to comment Share on other sites More sharing options...

1967spud Posted May 20, 2009 Report Share Posted May 20, 2009 uniforming and deburring the flash hole are more important to accuracy than any thing Link to comment Share on other sites More sharing options...
Grouse Posted May 21, 2009 Report Share Posted May 21, 2009 Thats a good question Oly, have a KandM in large primers and an adjustable in small primers. Some batches of brass "allow" a nice clean up by the tools, but other batches have a clean up rate of 70% - 85%, agree it would be nice to have a 100% cleanup but wouldn't want to go too deep (this is with fired brass). Anybody got an answer? Link to comment Share on other sites More sharing options...
Oly Posted May 21, 2009 Author Report Share Posted May 21, 2009 It's the K&M adjustable larger primer one that I have just bought, but I don't want to start uniforming at too great, or too little, a depth - hence the question really. I use Lapua brass, so it should be pretty good, but I just wanted to check before I go carving it all up! Link to comment Share on other sites More sharing options...

Oly Posted May 21, 2009 Author Report Share Posted May 21, 2009 no, it's definatly a depth adjustable uniformer. Sorry, no pics at present Link to comment Share on other sites More sharing options...
JC275 Posted May 21, 2009 Report Share Posted May 21, 2009 I am often guily of over simplifing things so I could be wrong but I just measure a primer from the batch that I am going to use then set the cutter depth to that. As Nightwalker says, some clean up right to the bottom of the pocket and some don't but at least I shouldn't be making the over deep ones any worse.

auquhollie Posted May 21, 2009 Report Share Posted May 21, 2009 I have the K&M uniformer but have stopped using it. I found that it was wearing away the primer pocket wall and causing premature slackness in the primers. I have since prepped a new batch of brass by doing the flash holes, neck turning and shamfering the case mouths and not touching the primer pockets. Not noticed any difference in the group sizes.
