The .32 H&R Magnum
The .32 H&R Magnum
The .32 H&R Magnum

(show above is .32 S&W, .32 S&W Long, .32 H&R Magnum, .327 Federal Magnum)
(bullets: 100 gr plated, 100 gr RNFP, 115 gr RNFP & 113 gr CPB with Gas Check, Berry’s HBWC 83gr(copper plated)

Loads for the .32 H&R Magnum:
(Note: Most ARE MAXIMUM loads, you may want to use 10% less to start.)
(See note on Powders below or read all about various Powders.)
You can shoot the .32 S&W and the .32 S&W Long in the .32 H&R Magnum since all are shorter cartridges than the .32 H&R mag. but the same bullet diameter. The .32 H&R case is quite strong and some shooters are using this case in their .327 Fed. Magnum guns and pushing the max loads. You are on your own if you do this.
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.

Bullet size is .314″ (lead)(some .313″) and Jacketed is usually .312″ in diameter.

(Note H110 & W296 are the same as of 2008 as is HP-38 & W231)
(IMR 4227 is same as H-4227 if made in Australia)

* These loads shot in a .327 revolver, may be too hot for a .32 H&R.

Discussion: All the powders listed are fast to medium burning powders in small quantities for these lighter bullets. The JHP would be the defense bullet to use.

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