Uniforming primer pockets????

[Ned Ludd]

K&M tool here, it's awesome. However, I never use it with Alpha Munitions brass. The primer pocket has some kind of a bevel at the bottom corner and it would be nightmarish to attempt to remove it with the uniforming tool with a large number of cases. To remove any little bits of carbon from the corners of Alpha brass, I simply run the tip of an awl lightly around the inside bottom corner of the primer pocket.

Like many others, a pair of Sinclair unifomers since the early 90s.

K & M tool. I've used it for many, many cases, and still sharp.

Another vote for K M

Another happy Sinclair user here! Non adjustable carbide.

I noticed the different shape of the primer pockets too. I did no uniform them. I'm going to shoot them as they are.

I used an RCBS non-adjustable carbide unit for years, since around 2004 or so. It got stuck in a piece of Hornady brass back in August. I put the uniformer in a vice and pulled the brass off with vice grips. As it turned out, the cutting blade fractured and came apart, causing it to get stuck in the case. I purchased a new non-adjustable unit from RCBS and it barely touches the primer pockets on the same lot of brass. It really makes me question how consistent the uniformers are from tool to tool. I mostly use Lapua or ADG brass, but tend to uniform Hornady, Winchester, Federal, etc.

If you got this one. It is adjustable. Loosen the grub screw, add mild heat to the black portion, the screw stem has a hex style where you can put a hex key and turn to remove the carbide insert as your putting heat and some pressure on the screw The carbide insert is glued with locktite. I then clean it, and then use the screw to adjust depth of cutter. Then tighten the grub screw.

The Sinclair cuts deeper than the K&M but have damaged a few flutes over the years using the Sinclair on mil brass. The K&M is tuff kit to damage. Both very good .

Ive been using the Sinclair since the late 80's. Chuck it in my drill press, and hold the case in my hands.
On a slightly different note, I wait to do the uniforming step until I have fired the brass once. My thoughts have been verified multiple times throughout the years. When you fire virgin brass, all the dimensions change to some degree even if it's only a couple of tenths. I have uniformed virgin brass pockets, fired the brass and found I was taking off a little more the 2nd time around. Now I wait and it's truly one and done.
I hope this helps,
