Sellier & Bellot 32 S&W Long Ammo 100 Grain Round Nose Box of 50

Last reviewed: 2026-04-18 by Jake Terry, FFL07/SOT3, NRA-certified firearms instructor.

The 32 S&W Long occupies a narrow but enduring niche — gallery loads, bullseye competition, and light-kicking practice in K-frame and I-frame revolvers. Sellier & Bellot chambers this 100 grain round nose load in reloadable brass with Boxer primers, delivering 886 fps and 174 ft-lbs from a 6-inch test barrel. The Czech firm has been rolling ammunition since 1825, and this box of fifty reflects that institutional knowledge: consistent ignition, concentric seating, and velocities that track within single-digit standard deviations across multiple lots.

Performance at a Glance

The 100 grain round nose bullet is a smooth-feeding profile — no sharp shoulders to hang up in tight chambers, no exposed lead base to shave and foul the forcing cone. Muzzle energy sits at 174 ft-lbs, enough to punch clean holes in paper and knock steel at bullseye distances without over-penetrating backstops. Recoil impulse is mild enough for new shooters and sustained strings, and the brass cases eject cleanly from both swing-out and top-break designs.

This load suits the 32 S&W Long chambering — do not attempt to fire it in 32 ACP, 32 H&R Magnum, or 327 Federal Magnum without verifying chamber compatibility. Brass cases are reloadable, and the non-corrosive Boxer primers simplify decapping and resizing for handloaders. Find more options in our 32 S&W Long category.
