Calvin has. And done so with some pretty impressive results. I'm sure he can add more.
I understand your concern. It does seem to be one of the "non recommended" BPs. Calvin's results did not support this. He had great ignition.
Maybe, just maybe, TC wasn't just spouting off marketing BS when they made this statement about the BD:
T/C?s Flame Thrower ignition systems provide three times the volume of fire than conventional systems provide. 80% of the priming fire is directed into the main powder charge (versus 50% for conventional systems) and the patented design throws a ?ring of fire?, reinforcing the main core of fire, into the powder charge. This 300% increase of primer fire makes the Black Diamond? XR one of the most dependable modern style in-lines there is, even in the most adverse weather conditions.
Of course, that statement was made at a time when Tony's original design was really the only game in town. I'm sure newer designs are even hotter. Obviously, I'd rather have a sealed breach, but such an animal in a 45 with a 20 twist no longer exists (without going custom).
It better work, I found two of the old 45s with a 20 twist and they should be on the porch next week
I'm not expecting them to shoot a .40, BUT all preliminary indications support that they should stabalize a .358
Please let us know if you shoot BH out of your BD.
