Just wondering on the steel mixture on some of your barrels.



Some are listed as "4150 CMV", others are "4150 Chrome Moly", and some simply state "Chrome Moly Vanadium Steel".



Can someone shed some light as to what the barrels are truly made up of?



(the examples I'm pulling from below)

All the barrels that you referenced are made of 4150 CMV, CMV stands for "Chrome Moly Vanadium", the barrels listed are also QPQ treated inside and out. Hope that helps, thanks for the post.
