Dry fire if you cannot get to the range. Jmo
Way back then dry firing was common advice. I used to quite a lot, until one morning when sorta simultaneously making coffee and cleaning the revolver I picked it up, aimed and dry fired and put a bullet through the wall. Between bouts I had poured a cup of coffee and loaded the revolver, came back a few minutes later and “BANG!”. I had forgotten I had loaded it.
Since then I will NEVER put into my subconscious an expectation of pulling a trigger without consequences as dry firing does
