I've got K&M and they are great. Well made.

I have the K&M gauge tool.  It is a very nice piece of machinery.

Been using the Century 21 priming tool since it was recommended to me by fellow high power shooters several years ago.

Once you use one you'll wonder how you ever lived with anything else. Like the K&M, a bit expensive........... but, the proof is in the pudding and it adjusts in something like 0.005" increments for seating depth. For instance, R-P brass needs to be let off 2-clicks on the adjustment from Starline brass due to the slightly different rim thickness. Comparing it to a Lee or one of the cheap models is like comparing a $300 Russian shotgun to a Perazzi, etc. As any good high power benchrest shooter will tell you, consistent primer seating is just another key to good accuracy. Do it the same every time.

I've been using the K&M since the early 90's.  Another one to look at is a Lyman 310 priming die in the nutcracker handles.

Boats,

I have a bunch of the lee primer tools.  Been going to ebay them.  Some of them I just have the plastic tray, but not the punch and spring.  What plastic parts do you need?

Hi Boats. Are you using the tray type Lee priming tools that feed the primers, instead of loading them in the tool one at a time?

Though it's a bit pricey, I've been considering the 21st. Century auto feed that uses the Lee tray and shell holders. It looks to be well made and seems to have a very convenient depth adjustment feature. Not to drift off of your topic, but I wonder if folks have tried that hand primer?

I've been using the same Lee hand priming tool for over 2 decades, and thank God it's still working! Mine is one of the early versions with the round primer trays. I found another NIB at our local gun show for $5 a few years ago, and grabbed it up, in case I ever wore out my first one!
