I think this might just be an idea that should not have been run to completion. I for one would not trust a switch or a cut off to make sure that the damn thing did not ignite just as I pushed the bullet down. I am a little nervous just loading quickly if there might be any sparks in the bore. I have done it hunting and never had it go off but I am very careful to not have my hand over the ramrod. In fact the one thing I like about the Hubbard ramrod for the NEF is that it is two inches longer that stock which allows having your hand wrapped around the rod when the bullet goes to full seat. Just read about someone that ran the ramrod through his hand with a similar accident.
