I used to go shooting to relieve frustration(generally with myself). Might do it agian if things continue way they are in my life and it doesn't warm up soon.
Need to pick up some magnum shells for 12ga though. I like to beat shoulder up with a good stiff recoil to help deal with the frustration. Used to do it with the 16ga autoloader(second recoil of barrel slamming to back helped), but now just have the pump shotty.
Always crupulously follow safety rules, jsut that shooting lets me not think about my problems for a while. When it's warm out, I tend to ride my bike now to deal with frustartion. THat's different though, as riding bike gives me time and solitude to think, shooting lets me not think about the problems for a while. Two different forms of escape. Either one is better than hitting things, like I used to do(don't have a good place for a bag in my apt). Have ent in headliner of truck where you can see that I've broken the cardboard layer of headliner.
Long ago, when I still lived with my parents, used to take aluminum baseball bat out to big 70-80 yeard old chinese elm. Big thick bark on taht stuff kept me from hurting the tree, but sure sapped energy fast. Axe or hatchet and the three foot stump left from old cherry tree(which was now just well seasonsed, HARD hardwood) dealt with lots of frsutration over the years too.
There are other things on my list, but yeah, something good and physical tends to be the way for me, choosing the exact one ofr that time depends on whether I want time tothink about what's frustrating me, or some time away from the frustration.
