I recently picked up a T/C Black Mountain Magnum Westerner in .54 caliber. On the first range session I was shooting Hornady Great Plains conicals with 100 grains of Pyrodex RS. Unfortunately, after 18 shots I noticed cracks forming on the stock in the tang area. One crack on top and another on the left side. I made a repair with pins and epoxy but the cracks opened on the second range session. I am considering stock replacement but google searches can’t locate for this specific model. I’ve read in older posts that the BM Westerner is essentially a New Englander. Is that true will my BM Westerner barrel fit a New Englander stock?
