What's the most accurate tool to get consistant primer seating depth?

    I use the RCBS automatic priming tool. It's fast and works but its not consistant enough for my liking. I try my hardest to put the same amount of pressure on the handle when I prime each case. But it clearly doesn't work out as I plan. I can tell just by looking at the primers depth that they don't all seat the same. And I can even feel the difference when I go over the primer with my thumb. So for best accuracy I want something that seats them securely in the pocket, all at the same depth!

    I think you need to purchase a primer pocket uniformer.
    It is a cutting tool to cut all primer pockets to a uniform depth.
    I believe many reloading tool manufacturers make their own type. I use the RCBS uniformer that ia used on the electric case prep station and I have had no problems with its function.
    Good luck. JW

    I agree with JW.Get a pocket uniformer. Mine is from Sinclair and I've cut thousands of primer pockets with it. It never needs any attention and is just part of my routine
    case prep.

    I like to seat primers by hand. I have an RCBS and K&M hand Priming tool. I really like the K&M because it is much Heavier built. You can feel the primers bottoming out. I also have the Sinclair uniformer.

    A hammer...

    Just kidding!

    Uniform the holes as stated. I also give the case a half turn after seating a primer and then give them another go.

    All benchrest shooters seat with a hand primer. There is a good reason for that. You can feel the primer going in and bottoming out. You can accuracy by seating to deep or not enough. Matt

    I fitted an adjustable scew to my rcbs seater, now I can only seat to a certain depth and be more consistant. I tapped a hole through the handle and fitted the screw which pushes againts the body.

    Are you talking about an RCBS hand primer? The hand primer i had if you took out the piece you put the primer in; it would screw farther in or out and control depth. It is threaded in between the spring and end.
