When you're loading something as big and brawny as the .500 S&W Magnum, you want confidence that every round you build is going to drop into the chamber and run. That's exactly what the L.E. Wilson Pistol Max Gage 500 S&W is for. It's a caliber-specific, precision-machined gage that checks your finished rounds against maximum cartridge dimensions, so you catch problems at the bench instead of at the range.
Unlike gages cut to minimum chamber dimensions, Wilson's Pistol Max Gages are made with special-cut reamers to confirm a loaded round meets maximum cartridge spec. In plain terms, if your cartridge fits the gage, it should fit any firearm chambered to SAAMI specifications for the .500 S&W Magnum. The gage reads the dimensions that really matter: mouth diameter, base diameter, rim thickness and diameter, case and overall length, and bullet diameter.
Using it couldn't be simpler. Make sure the gage and the cartridge are both clean, then drop the round in. If the head of the case sits even with or below the gage surface when you set it on a flat surface, you're good to go. If it sits high, that's your cue to tweak crimp, seating depth, or your resizing before the round ever touches your revolver.
L.E. Wilson has been building precision reloading tools for over 80 years, and that reputation shows up in the feedback from folks who load with these gages. The accuracy and craftsmanship get mentioned again and again, especially for spotting case bulge and confirming overall length. It's a one-piece tool with nothing to adjust or knock out of calibration, which makes it a dependable go-to for anyone running big-bore brass.
The tolerances are tight on purpose, so keep the gage clean and free of grit for the most reliable readings. For the handloader feeding a .500 S&W, it's a small tool that saves a lot of time and headache down the line.
It checks all the critical dimensions of a loaded .500 S&W Magnum round against maximum cartridge specifications. That includes case mouth diameter, base diameter, rim thickness and diameter, case and overall length, and bullet diameter. If a round fits the gage, it should chamber in any firearm cut to SAAMI specs for the cartridge.
You can use it on loaded ammunition. Drop the finished round into the gage, set it on a flat surface, and check that the head sits even with or below the gage surface. It also works for checking resized brass, so it's handy at a couple of points in your loading process.
Most pistol gages are cut to minimum chamber dimensions, but Wilson's Pistol Max Gages are made with special-cut reamers to confirm a round meets maximum cartridge spec. This makes the gage a bit tighter, which is exactly what you want for catching bulged cases and oversized rounds. Keep in mind a round that won't enter the gage may still chamber in some pistols, since the gage is built to the max cartridge standard rather than your specific chamber.
A round sitting high usually points to an overall length that's too long, a crimp that's too large, or a case that needs more resizing. Make sure both the gage and the cartridge are clean first, since any debris can throw off the reading. From there, adjust your crimp, bullet seating depth, or sizing until the round sits flush.
