i have saved quite a few empties from my trips to the range and i didnt think you could have so much fun dry firing but..... i have been doing it scince i read the tip on using a spent case to save your chamber . i have "shot" about 500 squirrels and probably half that in crows and the cat that leaves paw prints all over my cars has theoretically ran out of its 9 lives about 15 times over.
When i did go to the range to let some real lead fly i found my trigger controll has improved so i would reccomend everyone at least grab a few spent shells and take em home, i dont know about everyone else but i live in the city and if i fired my gun the cops would be here in about 30 seconds, the cop shop is like 2 blocks from my house, but i can dry fire all i want without waking the neighbors,
I think it would be a good thing for even the most experienced shooter to do. no matter how long you've been shooting there is always something that you can do a little bit better. oh thanks to joaquin B for the tip on stuffing tissue paper in the case to stop crud from entering the barrel.
just to see what would happen i didnt plug one shell. and the amount of crap that flew into my barrel was surprising. it was about a pinch of fouling and wahtever else is in there(a pinch is a cooking term for those wondering. basically its about the amount of pepper that would come out of a shaker if you turned it over and back real quick. not alot on food but definatley bad for your
