    I've been looking for Starline 45 super or +P brass, to no avail. I checked with Remington about their +P and was told it is identical (aside from the nickel plating and head stamp) to their standard pressure brass.

    Is there a manufacturer in addition to Starline that produces beefed-up 45 +P brass? Probably out of stock anyway, but I want to know what else to look for.

    The difference in pressure between .45ACP and .45ACP +P is only about 2000psi, so if you are looking to do real heavy loads, +P isn't the way to go. It equates to only about 150fps increase. And, as Remington told you there usually isn't any difference in the cases except for markings. The Super jumps up another almost 4kpsi, or 28kpsi vs. the 22.7kpsi for the ACP. So you can get quite a bit of velocity increase there.

    If you want heavy loads, the Super is it, but make sure your gun is able to take it. Keep looking, somebody out there has some brass for sale.

    Starline's +P appears to be closer in spec to their 45 super brass than their standard 45 acp. Same case volume and thicker web on both the super and +p. I guess that's an anomaly among manufacturers.

    Does anyone know of another manufacturer of 45 super brass?

    With my cross sections 45 Super from Starline is the same as any other 45acp brass.
    But 45 +P from Starline is thicker walls and less internal capacity.
    The above is NOT the same as the finding of Joe D'Alessandro [real guns].
    He finds just the opposite.
    I got my first samples of Starline 45 Super and +P in ~ April of 2000 and he got his sometime earlier than that.
    My little 24 ounce Para Ord P10 has terrible case support with .235" feed ramp intrusion from the breech face. 45acp brass has a .180" thick web. Using Starline 45acp +P I am able to finagle 45 Super performance from that pistol. Recoil is another problem.
    I have a 20 ounce Patriot 45acp with case support at .180" that I can shoot 460 Rowland loads with mixed used 45acp brass. Recoil is another problem.

    Unless you've already done this, I would procure some new +p brass and some new standard brass, then track and load each with identical loads, then see if +p actually does make a difference. Who knows, it might be w worth while choice? But I honestly think that since 45 acp is such a low pressure cartridge, even with +p loads, that I seriously doubt your going to see any noticeable advantage.

    From Starline's website:


    45 Auto +P Brass 45 ACP+P, 45 Automatic+P
    0.892 - 0.897 O.A.L.
    The 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 water capacity than the standard 45 Auto.

    My initial supply of brass for any caliber often comes from buying loaded ammo and unloading it at the range.
