Hi John, if you are shooting HFT with your Gold star you will have to take the bubble off, not allowed I am afraid, in FT yes but not HFT. You are allowed to leave it on if it is taped up.
I got to shoot a production .177 Gold star today at the shooting show. Simon Harrison is manning the BSA portion of the ATEO range with one a .177 single shot that you can try for yourself.
HFT, for people with only 2 buttucks!
