A new (to me at least) YouTube channel called 2AlphaGear posted this video recently where they ask the professional shooters about the number 1 thing they do to prepare for a match:
The number one answer: gear checks.
Randi Rogers mentioned getting in some dry fire before heading out to the range, but for the most part all of the shooters interviewed talked about checking gear instead of trying to get in tons of last minute practice. As Steve Anderson always says in his podcast, the last minute practice won’t help you, its the consistent practice every day that gets Match Guy ready for Match Day.
