This is really important and something EVERYONE here needs to do NOW!!! If you don't want an illegal shitshow when you die, any firearm you own has to be exactly specified where you want it to go.
In my case, since wifey isn't really fond of my hobby, I added specific instructions in my will where each firearm goes (to my boys). This way, wifey doesn't even have to deal with it (since everything else transfers to her), my sons know exactly what needs to be legally done.
I'm a new gun owner and just took a course this past weekend. I'll definitely need to get some dummy rounds to practice loading, unloading, and just holding up a long gun before I feel confident enough to shoot live ammo at the range again. (I am female so my lack of upper body strength does not help at all.) The ones we used in my course were Snap Caps with brass on the end, but when I look online for dummy rounds, I find not just that kind, but also a lot of 3D printed stuff. Anyone ever tried it, and would it be advisable to buy?
Here are some photos from some eBay listings. (These are not my listings and I am not advertising them.) I would be buying 12ga but I've also seen 9mm.
