Hello all, hope everyone is in good health today. I have built several Muzzle loaders for myself, rifles and pistols from scratch using 4130 or 4140 stock for barrels. My father brought me a 5 ft long x 1 1/2" wide piece of 6 sided 306 stainless steel stock and said here make a rifle with this.Not wanting to disappoint him I thought I would ask the collective here. I know BP has a low chamber pressure but what do you guys think, would the 306 SS be ok for a 45 or 50 cal. muzzle loader barrel? Thanks in advance for any recommendations.
