    some of my 30-378 brass will not hold primers. some are loose. brass is expensive. is there any way to save them.

    Assuming this isn't new brass, loose primers mean the brass is toast. If it is new brass, maybe it is a bad batch? Pushing loads too hard can increase stretch and decrease brass life. Throw it out and start over IMO.

    Yes they actually make a tool to tighten them. I believe RW Hart and maybe RCBS makes one. How many firings on your brass?

    GG did an evaluation of the primer pocked swage tool. If I remember correctly the thing got mixed reviews tending towards the low side.

    I've discovered that two very small drops of super glue applied with the very tip of a tooth pick with the super glue applied in two spots opposite each other on the primer pocked bearing surface works very well for me.

    The down side is that moisture has a very easy path to the powder. If you use ice to cool the cartridges ensure they are are in a water tight poly bag.

    I've noticed no blow by indications and run pretty fair pressures in a 270 Allen Mag (otherwise I wouldn't have such loose primer pockets so quickly).

    Some of the pockets are loose enough that I seat the primer with my thumb. But be careful with the super glue and the thumb. Use rubber gloves if you're sloppy like I am.:)

    Just ordered mine off his online store hope they are what their cracked up to be. Considering how hard it is to get brass these days it should be well worth the money.

    Thanks fella's

    Haven't tried the Hart tool, but it'd be worth a shot. In the mean time, you migth try switching primers, depending on what you're already using. The CCI primers tend to run a bit large, and will "cure" the problem for another firing or two, maybe even more. This isn't really a "fix" a much as a stopgap measure, but there ya' go.

    I find that if my primer pockets are getting loose even after multiple firings, I am running too much freakin pressure. I back off the load and keep my pockets tight. If a load is expanding pockets, its too dang hot.

    Michael,
    And here I was trying to find a nice, polite way to say that. It's a limiting factor, no question, and needs to be read as such.

    Michael, Kevin,

    Squat, that ain't no fun:D

    I still like the super glue thing.:rolleyes:

    I really feel that as my wind reading abilities and my shooting confidence improves the pressures will decrease.
