Cowboy Chrony Loads .38 Special 105-gr Lead

[Morne]

With the sun coming out and the temperature getting above freezing I felt the urge to go chrono some potential cowboy loads:

Really, it looks like the 3.1-gr of Red Dot pushing a 105-gr lead bullet is more than sufficient for CAS purposes.

Both the SWC and TC profile fed well enough in the lever action M92 carbine.

Please note that these are the first lead bullets I have ever loaded and shot. EVERYTHING before this was copper plated or jacketed.
