Also useful cleaning the crud out of dirty fired pockets.

You can also buy adjustable ones.

The KM is adjustable if you think you can set it better than the industry standard depth they are preset to. Small Rifle/Pistol is set to 0.122" Depth.

I've seated many thousands if not ten thousands of primers and over the decades never had one failure.
I also like my many competition friends use a KM Primer Seater, load one primer at a time and feel it actually seat to depth in the primer pocket. One friend was using the 21st Century Primer Seater and suffered numerous misfires. On examination most all his primers were not seated to the pocket bottom and proud of the case head. He didn't read the instructions properly and had not set the tool correctly so it wasn't travelling far enough.
I absolutely hate the idea of using a Press to seat primers, very little actual feel as to when the primer has seated correctly, very easy to crush a primer cup with too much force... Bit like the Lee and RCBS Primer Seaters....lack of feel and adjustment.
Apollo wrote:I don't think anyone was talking about millimeters depth wise but there is an ideal depth and it certainly is below case head a thou or few maybe. Considering also that not all primers are the same height, nor diameter or even cup hardness especially Small Rifle Primers. Yes, the bottom of the primer pocket edges ideally needs to be square not curved which helps to seat every primer the same.
The OP is probably not talking about OCD Accuracy for Benchrest but I reload everything I do with that in mind even for my non competition reloads. I really doesn't take that much more effort or time trying to get everything spot on as best I can. Most everything I shoot is capable of at least 1/2 MOA accuracy, competition well way more accuracy is required to stay at the top in Benchrest. My problem is getting way too old so I'm the failing part.
I don't scrimp on any components and buy the best I can afford including custom made bullets.
I get pretty upset if I go out looking to cull some varmints and have even one miss. Take 10-20 rounds out and get the same amount of kills. Maybe that Rabbit out at 300m might be a challenge on a real windy day but one can always decide to not take the shot and save it for another day. Advantage being at home and picking your conditions to have a bit of fun.
