    I just got some 147gr Gold Dot bullets and decided to load up some test rounds tonight. I found that with CBC brass, the bullets are bulging the brass so much that they don't fit the chamber of my pistols at all. They get stuck about half way, 3/4 of the way in the chamber.

    No problems with Win or other brass so far and the CBC cases work fine with 124gr and 115gr bullets.

    Anybody else experienced this and have any remedies? I'm guessing the only thing I can do is separate these from other brass.

    First thing I'd do is check the diameters of the bullets with a micrometer, the 147s and the 124s and 115s that work well.

    Make sure it is diameter and not OAL. CBC has never been a favorite brand to reload for me. I believe their brass is thick and that may cause this problem.

    They should be 0.355".

    I'll check my caliper then re-check the bullets.

    After a little more searching I'm seeing that some brass have thicker walls (like dwarren123 already mentioned as a possiblity) than others and that seems to be the issue with the deeper seating 147gr bullets.

    I use Zero 147gr JHP's because they have a rebated base at the point where the case wall begins to thicken. I use a single stage press. Because the rebated base allows the bullets to be pressed in to unbelled cases, I don't have to bell the cases or taper crimp.

    Try better brass like Winchester or Federal.

    What type of press/dies? what type of gun? factory barrel? I use CBC (Magtech) brass sometimes and don't any have problems.

    Dillon SDB with stock dies. M&P 9FS with factory barrel.

    I've never had any problems with CBC brass until I got hold of some 147gr bullets. I've got some Berrys 124gr hollowpoints that I have to load deeper than usual so they seat in the chamber properly and they've loaded fine in the CBC brass.

    Do you have a picture of one? I don't fully understand what you're saying.

    Have you done any testing with those bullets or their 125gr HPs?

    The more frequently used term would be 'bevel base' bullet. Google one of the mould manufacturers, such as Lyman and view their mould designs... what you're looking for will either say 'bevel base' or be abbreviated as BB.

    I know they show a 148 grain BB wadcutter... I've been casting with that mould for well over 40 years.

    Ohhhh....yea, that makes more sense. He lost me with the "rebated base". I can see how that would be beneficial. Thanks Jack!

    Bullets don't load any easier than these:

    Very cool. I didn't realize they made their bullets that way.

    I'm curious about how well their hollowpoints perform.

    Only the 147 grain 9MM JHP uses the rebated design. As for performance, they are very accurate bullets and a delight to load. If you're referring to defensive ballistic performance, I have no idea. It's very difficult to equal or exceed the current crop of factory defensive loads in most calibers so, I have no interest in doing so.
