CSA .40-70 Straight success finally...kind of

[throck3]

My firing pin wasn't the problem. Sometimes they simply break. It was easily replaced and I kept an extra as a spare. And yes, be real careful about putting that hammer on half-cock before lowering the breach block. You can easily shear the tip of your firing pin. I'm pretty sure my issue was a combination of the need for more powder and correct placement of the front rest. After I fixed that, I shot six consecutive shots into and inch or less.
