    You said the dummy round you pictured in you 11/16 post was ok, and left no rifling marks. What have you changed since then?

    Clean your shellholder, crud can accumulate there and cause issues

    Bird. Your right. I had minimal success it seems. So in my frustration I began taking apart these cases. All dropped into the chamber completely no issues there, so I began taking measurements and found on the boolit a that would not chamber the nose read .300-.302. On the boolit that did chamber .298. So now I need to figure out by the variation of the nose. Could it be the lube a matic? Seating stem of die? Seems to me the throat on this is very narrow

    I need to invest in a nice mold it looks like. Anyone have suggestions with a narrow nose?

    If your .298 bullet came from the same mold and alloy, you need to ask yourself what you did.
    If I want smaller diameter bullets I would get the mold hot and cast frosty bullets, and maybe even quench them.
    If I wanted smaller still, I would add more pure lead to the mix.
    What alloy are you using?
    I have had bullets that are 2 thou oversize and are engraved by the rifling when chambered. The action closes with a little resistance, if the bullets are not too hard.

    After a few happenings like this, I started doing my crimping in a separate die. It cured most such problems. Yes, there's the added expense of a crimp die, but the results are worth it.

    Hasselbach:

    Don't give up!

    From the picture in post 40, it looks like your barrel was rifled
    with the same tool as mine, a Marlin 30AS with microgroove
    rifling.

    If the engraving is on one side of the boolit, concentricity in
    seating is likely still an issue. I mentioned my solution earlier.

    Also, the advice Outpost 75 gave me is appropriate:
    get a mold that casts a nose more suited to your rifle.

    Having said all that, I use Lee and NOE push-thru
    sizers so there is little possibility of plumping up
    the nose diameter as may be happening with
    your lube-sizer.

    End result for me: my 30AS is now a tack driver.

    An issue I found when loading for my .308s with Lee dies was when my die was set too long in the press my bullets would not be concentric. I screwed the die down to nearly touch the case mouth and seated the bullets and the problem went away. This may be an issue.
    You can miss fast & you can miss a lot, but only hits count.
