I'm sure with your experience, you should not have any problems. We will all be anxious to see the finished product. Now, not on this kit but one other, is the proper alignment or contact between the hammer cup and nipple. Ideally
, it should be a good square contact. There are times when I get mis-fires and I print a deactivated primer to see how I'm hitting. Your kit should address this right off and don't percieve you having a problem. ....
Good Luck and;
Be Safe !!!
