I agree with Jerry V.
I'm not a great shooter, never will be either.
But to me the whole beauty of watching a really good shot,hitting flying targets is the lovely fluid action of the mount, swing n follow through.
Its lovely to watch....pre mounted leaves half the skill out, I think.
What ever the purse of a Pigeon shoot,I think the winner should be the bloke who can get his gun up,swing well & hit whatever is the target.
Taking out the mount seems to me like taking half the skill involved away.
The scores probably go up, but I don't see that means better, controlled shooting.
you have one too,Dr Wonko, smile
cheers
