I have the 7mm throating reamer but at this time, I need more testing before offering it to the public. If it works, I will get these reamers in all the more popular calibers.
It will not effect what dies you use or fireforming brass in any way, its a dimensional change in the throat design is all, not the chamber design.
My real concern at this point is how long the throat design will last with accurate performance. I have to get that determined before I will offer it as a custom option for my customers.
