Description
Starline has earned its reputation among reloaders for a reason, and this .460 S&W Magnum brass is a prime example of why so many handloaders reach for it first. These are factory-new, unprimed cases made to precise specifications, so you get consistent concentricity and controlled wall thickness right out of the bag. That translates to smoother bullet seating, better chambering, and the kind of lot-to-lot consistency that makes load development a whole lot less frustrating.
The .460 S&W Magnum is a seriously impressive round. It started life as a lengthened .454 Casull, and Smith & Wesson bills it as the highest-velocity revolver cartridge in the world, pushing a 200-grain bullet north of 2,400 feet per second out of a long test barrel. With that kind of performance comes serious pressure, which is exactly why case quality matters so much here.
What Sets This Starline .460 S&W Magnum Brass Apart
Starline cases typically run so true that they generally don't require resizing before your first loading, though checking length and giving them a quick prep never hurts. Case length runs right in the 1.790 to 1.796 inch window, keeping you squarely in spec for load development. Because this brass is strong and uniform, it holds up well to repeated resizing and reload cycles, so you get real value over the life of each case.
Primer Notes for the .460 S&W Magnum Handloader
This is one of those cartridges where primer choice genuinely matters. The .460 S&W runs at pressures up to 65,000 psi, so it's built around large rifle primers rather than pistol primers, which use a thicker cup suited to those higher pressures. Hodgdon recommends Winchester Magnum Large Rifle primers for this round, and sticking with proven data from a current load manual is the way to go. Whether you're feeding a big S&W X-Frame revolver or a single-shot like the T/C Encore, this brass gives you a solid, reusable starting point for building serious .460 loads.

Frequently Asked Questions
What primers does the .460 S&W Magnum brass take?
These cases are set up for large rifle primers. The .460 S&W Magnum runs at very high pressures, so it uses large rifle primers with their thicker, tougher cup rather than pistol primers. Hodgdon specifically recommends Winchester Magnum Large Rifle primers for this cartridge, so pair these with a proven load from a current manual.
Are these Starline cases primed or ready to load?
They ship factory-new and unprimed, so you'll prime them yourself as part of your loading process. Starline brass is known for tight tolerances, and these cases generally don't require resizing before the first loading. A quick inspection and length check is always smart before you charge and seat.
Can I use .460 S&W Magnum brass for other cartridges?
Yes, this brass is the parent case for a few wildcat and specialty rounds. The .45 Black Powder Magnum uses an unmodified .460 S&W Magnum case, and the .45 Raptor is built from this brass as a rimless AR-10 cartridge. Always follow published data specific to whatever round you're loading.
How many times can I reload this Starline brass?
Starline brass is built from quality material with controlled wall thickness, so it holds up well to repeated resizing and firing cycles. Reload life depends on your load pressure, your dies, and how carefully you prep, but reloaders consistently praise Starline for durability. Inspect each case for splits or loose primer pockets along the way and retire any that show wear.
