Good for you GK!
Chrise. I usually spot a solution first and then try to clue it. Shooting Gallery had come up in another context (fairground}. I always check and double-check my definitions, usually in Chambers, and I came across this other meaning whilst doing this. Then comes the clueing. I try to comfirm every synonym in at least two thesauri. I use an anagram facility in Crossword Compiler to wade through the many anagram words. This is more complicated when setting a "subtractive anagram" because the anagram words must, in general, tie in with the sense of the clue. There are many more devious paths to follow, e.g., try to link the main definition with another word (which must gel with the full clue) which suggests a different (false) idea in the solvers mind.
And, much more.......
I've never tried analyse this before and now am beginning to think I'm a bit 'twisted'...so I'll stop.
Ari! This side of the pond dog and hound are listed as synonyms in almost all thesauri. Aooooooooow! See! I AM loosing it! LOL. Lockily the moon is only half-full overhead here at present or I might be tempted to go loping across the moors.
Thanks ALL for such a fun response day.
Goodnight
