    Is WWB .45 185gr Brass different than .45 230gr?

    Since I know I am going to start reloading to feed my shooting addiction... I need to ask you fellow GTers if the Brass from WWB .45 185 gr. is different from brass from WWB .45 230 gr...

    The reason is that the brass looks the same and if I don't separate it from the beginning I will not be able to tell them apart. Since the 185 gr bullet is lighter, the load may be weaker and brass walls may be thinner....


    +P cartridges are thicker than regular ones, I want to confirm if all other cartridges have the same brass regardless of bullet weight.


    Thanks for the info...

    Nope shouldn't be any difference whatsoever.

    If this correct! How come none (Over 20) of my reloading manuals has no warning about reducing powder charges when using +P brass.

    Brass is the same in both regular pressure and +p pressure loads, the +p loads don't require different brass.

    All are the same.

    Part of what a cartridge case does is function as a seal when the charge is fired. It doesn't require any additional thickness to contain any "+P" pressures but it does need to be elastic enough to expand upon firing, no matter whether standard or "+P."

    I read somewhere that Federal +P brass was thicker. I tried to relocate the source and I found this:

    "45 Auto+P is a strengthened version of the 45 Auto with the same external dimensions. A thicker web and heavier sidewall at base strengthens the case in potentially unsupported areas. This case has approximately 2 grains less internal capacity than the standard 45 Auto. "

    Here's their link; look under "Product Information and Description" ---

    Good stuff Glock 45.

    If so then a hand loader would need to take the diminished case capacity into consideration when flirting with max hand loads. In the stubby .45 ACP case 2 grains amounts to an effective decrease.

    The only difference you may see is if they were WinClean ammunition which also comes in the white box. Check this thread and read post #5 for what I found out.

    Thanks hoss for linking that thread. I missed it first go-around. Never saw overlarge flash holes before. Would have to consider such when hand loading near max.
