RIFLES THAT RESPOND WHEN YOUR TRAINING TAKES OVER. Rock river Arms PRO-SERIES ELITE / AR1731 QUESTIONS & ANSWERS • Jeff John • NEW! Q: I have a question about the various old .32 cartridges. I know the The .32 Colt Shown with optional Operator stock Rock river Arms / LAW ENFORCEMENT / LE1070* .32 S&W Long is basically the same as the .32 Colt New Police, but what about the other .32 Colt cartridges? I recently found a Marlin lever action marked “.32 Long Colt.” My references only state some single actions were chambered for .32 Colt and some were chambered for .32 S&W. Could you please let me know what the differences are? Ed Galley via e-mail The .32 Colt (both Short and Long) used an outside-lubricated heelbased bullet (sort of like a large .22) when first developed. The .32 S&W and .32 S&W Long use a bullet of similar diameter, but the case is of larger diameter so the bullet can be seated with the grease grooves inside the case. The .32 Colt has a nominal head diameter of .318", while the .32 S&W and .32 S&W Long have a nominal head diameter of .337" (according to 2nd Edition Ammo Encyclopedia by Michael Bussard, available from Blue Book Publications, 8009 34th Avenue South, Suite 175, Minneapolis, MN 55425, 800/8774867, www.bluebookinc.com). The two are not interchangeable. In the late 1890s, .32 Colt ammunition was loaded with a smaller diameter hollow-base bullet seated within the case. An early Marlin catalog notes the Model 1892 fires either .32 Short or Long Rimfire or .32 Colt Short or Long centerfire and came with both rimfire and centerfire firing pins. If you were thinking of purchasing the Marlin, it would be prudent to determine which firing pin it has or if it comes with both. The only current load I’m aware of is loaded by Winchester, stock number X32SCP. The .32 Short Colt is loaded with an 80-grain bullet at a nominal 745 fps. As noted in the July’s Q&A, Brazilian-made .32 RF, both Long and Short, were imported in the 1990s by Navy Arms, but it is becoming scarce— and expensive.
