for the reasons stated before i use combination trigger locks. i dont wanna risk loosing a key or forgetting it. the key to my range tool box is always on my car key chain aswell. i bring my range box with me, soon to be replaced with range bag cause im almost out of room with it. it has all my cleaning stuff in it, multitool, ive always got a pocket knife on my hip and i use it all the time every day. its got a microfiber cloth inside, a large one, thats come in handy when i had missfire issues with my sks and stripped it on the field, better to put the parts down to clean and inspect them on a blue cloth then on a piece of wood or ground. always gotta have gun cleaner. shooting corrosive ammo through my sks i like to squirt some down the barrel when im done for the day. and the other day i went ti hit the mag release on my r700 and pushed the bolt release instead and dropped that on the ground. so it ended up getting cleaned with spray cleaner. safety glasses, 2 pairs as i often bring a friend. and lots of pairs of ear plugs. also a pair of thin gloves incase it cools down a little and im not done shooting yet. and now my spotting scope, which doesnt fit into the box so i need to find a nice range bag that holds more crap
