My next door neighbor is a Colt freak. He has a refurbished Colt New Service in 45 Colt (what else). He wants to shoot it! I loaded up some loads with minimum starting load levels from the Speer 14 Manual.
Using a 255 SWCL bullet and 2400 or 4227 the gun shot to point of aim both windage and elevation, and with good accuracy, but they both appeared a little too warm for this old warrior.
Cases were hard to extract and cylinder drug on forcing cone when attempting to lock cylinder in place without ammo in gun. No powder residue under cylinder star or lead residue on forcing cone or face of cylinder.
What's a good Trail Boss load with the 255 lead bullets, that would make this gun enjoyable without the risk of sending molten steel in various directions.
