Reloading The .38 Smith & Wesson


SWC= Semi-WadCutter, FMC= Full Metal Case, FMJ= Full Metal Jacket, JHP= Jacketed Hollow Point and if GC indicated, means Gas Check at bottom of lead bullet.

Loads for .38 S&W:
This short, little cartridge has been around since the 1870's and was most common in the "break-top" models. These types of guns are not as strong as more modern solid frame revolvers. Do not use anything but light loads and lead bullets in these older revolvers. The little S&W was a great concealable handgun and is used today in Cowboy Action Shooting in the "belly gun" or "pocket gun" category.

(Note: These ARE MAXIMUM loads, you may want to use 10% less to start.) Light loads for the "break-tops" are noted.
(See note on Powders below or read all about various Powders.)
Due to different barrel lengths, type of bullet, seating depth, primer type and other factors, you may not get near the FPS charted. It is just a guide and the reason you should start under these charges and work up.

These are ALL MAXIMUM LOADS: Start at 10% less and work up! Bullet size is .360" lead in diameter. You can use .358 lead which is normal .38 special size, and it will work OK, but accuracy may be affected.

Discussion: Fast burning powders are well suited to this small case. It's an old cartridge and if you use old guns, be very careful and use light loads and bullets. Note the nominal .360" used in the original guns, but where .357" or .358" bullets are used since they are more available.

A bullet with a copper gas check or copper plating is best for INDOOR ranges to keep lead vapors out of the air.
