I was looking into the world of cap and ball revolvers when I found an issue that hasn’t really been solved. Those that have a .36 cal muzzleloader know that it takes a .370-.375" diameter projectile. The conversions to a standard cartridge include:
Low powered 38 Sol
38 Long Colt
The problem is that these bullets need a hollow base to basically fire form to the lands and grooves. But .015" is a lot to stretch lead.
Then I came across this little gem, the 38-40.
It has a bullet diameter of .401" and is a necked down version of the 44-40.
Do you guys think it would be worth the while to attempt to convert a revolver to accept this cartridge? I know I will have to bore out the barrel and recut the rifling. Let me know what you guys think
