.32 H&R Magnum & True Blue & Ruger's LCR

[Shivahasagun]

I do think there is a benefit to stronger brass when used in some auto pistols, especially when 6'O clock case support isn't great.

IIRC, cartridges like .357 sig and .45 magnum have extra-strong web support.

As for .32 magnum & the snub...I have an LCR .327 and load .32 magnum.

Even loaded to it's maximum potential, from a short barrel the best you'll get is .380 acp performance. Unless your goal is maximum penetration, then you can load a heavier bullet than in .380.

It takes a .327 magnum-energy load to get 4 inch barrel 9x19 performance (Penetration & expansion) from a 2 inch barrel .32.

I'd love to be loading a mild (but hotter than .32 Mag) .327 load with something like Enforcer but unfortunately the brass is not available.

I've fired the factory Federal hydrashok 85 gr and it is indeed in that gap. Doesn't have all the recoil and blast of the factory Cci Gold Dot loads.

They are going to be mild on penetration, but not a bad load. I wish they used a 100 gr bullet.

Exactly. The brass is specified in ASM standards as an alloy of 70% copper and 30% zinc. Muntz metal is a less specific alloy used for cartridge manufacturing which can as low as 68% copper and 28% zinc with traces of iron, silicon and/or chromium. The internal specifications for each cartridge are in the SAAMI/CIP articles. Unless Starline is deliberately under sizing the interior dimensions by a significant amount, their brass conforms to standard and isn’t significantly different than any other brass.
However, that’s really beside the point. In a revolver cartridge, where the entire case is contained in the chamber, save for the rim and primer cup, aside from sealing the chamber, all the brass is doing during combustion is holding the primer.
Starline is not being untruthful, they’re just not saying the obvious part: all cartridge brass is the same regardless of the chambering stamped on the head. .223 Rem brass is also cartridge brass (or Muntz metal) and is just as “strong” as .338 Lapua Magnum brass (or Muntz metal).
I hope this helps because I’m running out of ways to say, the chamber is where all of the force is contained and the brass is just a gasket. Do not exceed chamber pressure specifications under the misguided notion that one brand or another of brass will mitigate the pressures. It’s not happening.

One obvious follow up: So Starline is inviting its customers to not just exceed but greatly exceed SAAMI specs regarding pressure when reloading their 45 Colt brass and knowing it puts their customers at great risk?

I don’t see how you make that jump….

One obvious follow up: Even tho Starline is obviously inviting its customers to not just exceed but greatly exceed SAAMI specs regarding pressure when reloading their 45 Colt brass, they’re doing so knowing it puts their customers at great risk?

Negative, Space Cowboy! Starline is stating the obvious: all of their pistol brass - be it .45Colt or .44Magnum - is of the same strength and is tested to the same standard. YOU implied (incorrectly) that there would be a different standard for one brass versus another depending on the chambering. Wrong. No way. You’ve been told repeatedly and choose to continue misinterpreting. That’s not on Starline, it’s on YOU. Stop thinking there’s one kind of brass for .22Short and an entirely different brass for .460Ruger. Nope, negative, nichts, nyet! Cartridge brass is cartridge brass. Muntz metal is Muntz metal. SAAMI and CIP spec’s are simply suggestions but they carry the weight of some liability protection because they are industry-standards. The only way Starline can place themselves and their customers at risk is if they deliberately and without notice alter the internal dimensions of a standard cartridge in a way which would increase pressures in an unpredictable manner. Increasing the material in the sidewalls, web, and head would do that.

No, just following your admonition never to exceed SAAMI specs when reloading. And 45 Colt specs are for very mild loads.

The same holds true for .32H&R Magnum. There is no such thing as a +P or +P+ .32H&R Magnum. Doesn’t exist. Strictly marketing speak, gun-rag lore and bad decision-making. Anybody who encourages loading the .32H&R Magnum to pressures far in excess of SAAMI/CIP maximums is not to be trusted.

That was from Handloader Magazine. They’re “not to be trusted”? Nor is Starline? Incredible!

Y’all be careful out there loading over book max, best left to experienced reloaders.
