This afternoon the new Knight Red Hot #11 nipples arrived in the mail today.
My curiosity took over and I decided to put them to the test...
With a capper I applied the RWS 1075+ cap on the nipple. Then tried to take it off with my fingers - didn't happen
The picture(s) hopefully will explain what I was testing for.
The flash hole is the correct size .031/32 - no drilling needed.
I think the search is over and the shooting/hunting can commence...
