In the years that have passed, since the standard QRBP was modified, i have used the CVA Blackhorn plug, and the Western Powders Blackhorn plug, and the modified standard plug. All three work good enough, i can not really tell the difference in their performance igniting Blackhorn. There doesn't really seem to be a compelling reason, to invest in the necessary drills, to do the modification to the standard QRBP. However, if one just likes to spend time out in the shop, that is reason enough.
