It is fun trying to master it. It's also bloody frustrating at times. I've wanted to get my TX by the barrel and lob it down the range more than once.
Mine is doing well with FAPs. I tend to stark a session resting on a long V shaped bag, filled with rice - it's heavy and stable. Once I manage a good run of decent shots, I then change to resting on my hand. If the session goes well, I'll try some standing shots.
As already said, there's no substitute for practice and, to be honest mate, if I can improve, anyone can.
