I have a CVA kit gun,1861 colt navy .44,that I built in 1983.My gunsmithing skills were somewhat lacking back then,Ive improved!!But the gun shoots great and has been very reliable.I know brass frames are frowned on,this one is still tight.Yes,I shoot light loads20-25 gr FFFg.My kit was actually made by ASM,I know alot of folks poo poo ASM cap-n-ballers but Ive have several and have had no issues.Shoot it!!
