This video details a reproduction Colt 1851 Navy revolver converted to fire .38 Special wadcutters, mimicking historical blacksmith conversions. It covers the mechanical modifications, ammunition compatibility, and practical use, including manual ejection and safe carrying practices. The conversion proved effective in competition, highlighting the continued viability of single-action revolvers.

Quick Summary

.38 Special wadcutter ammunition can often be used in .38 Colt cartridge conversion cylinders. This is because the wadcutter's flat nose is seated flush with the case, keeping the overall cartridge length short enough to fit, despite the .38 Special case being longer than the .38 Colt case.

Frequently Asked Questions

What modifications are typical for an 1851 Navy cartridge conversion?

Common modifications include adding a ring with an embedded firing pin, shaving the cylinder to fit the ring, and installing a spring-loaded loading gate. Chambers are often recessed, mimicking historical 'blacksmith' or field conversions rather than factory models.

Can .38 Special ammunition be used in a .38 Colt cartridge conversion?

Yes, .38 Special wadcutter ammunition can often be used because the flush-seated projectile keeps the overall length short enough to fit the conversion cylinder, even though .38 Special cases are longer than .38 Colt cases.

How were historical cartridge conversions like the 1851 Navy typically carried for safety?

Historically, it was standard practice to carry these revolvers with five rounds loaded, leaving one chamber empty under the hammer. This reduced the risk of accidental discharge if the hammer were struck.

What are the ballistic differences between .38 Colt and .38 Special wadcutters?

.38 Colt typically used a 129gr projectile at 800 fps with black powder. A .38 Special wadcutter often uses a heavier 147gr projectile at around 900 fps with smokeless powder, offering slightly more power.
