First, as for not firing "someone else's reloads" part of meI take a bit of offense to that. If you were lucky you would get to shoot my reloads. I have been reloading for forty years. Started in 1969. I have been a long time target/varmint shooter and needed the most perfect ammo I could get. I also needed custom ammo that would maximize the performance of my rifles. Only way to get that was to make it myself. I have reloaded and fired many thousands of rounds of ammo without a single problem ever. I can not say that for factory ammo. I shoot on average once a week so I reload a thousand rounds or more a month of .380, 9mm and .223. Outside of my .22 firearms I shoot nothing but my reloads. I also supply my brother and a couple of my closest friends. They trust their lives to my ammo, and they have good reason to do so.
Now, that being said, there are those out there who do not do as well. Lots of jokers have jumped into reloading with very little knowledge, or even good sense or judgment. I have seen several of them bust their rifles at the range due to overloaded ammo. Some have no knowledge of things like inspecting cases, what case length is, of how to anneal a case, etc. They don't use a good scale to measure powder or check bullet weights. (I use there scales and constantly cross check them. I know how important .1 grain can be.) They don't know about primers, powders, working up a load, etc. In short, as I sit here and think of it, I can see why some don't want to use reloads.
What I do say is that there are a lot of us out here that do know what we are doing. As for the ammo in the pictures, that stuff is rough looking and I wouldn't use it. I especially avoid cases with any discoloration (tarnish, not the normal annealing marks) The brass can be very weak and I see many of these cases blow out or crack when fired. This happens a lot with the old surplus ammo used at the machine gun shoots. These guys are running thousands of rounds through their guns at shows. They can't afford to use new Lake City, etc. in them for a show. They buy up old cheap surplus and shoot it. There is a reason that ammo is surplus. A lot of it is old and damaged and the military dumped it.
So, it it looks less than good, don't waste your money on it. Buy good quality ammo either NIB or from an experienced serious reloaded. I find it interesting that I have offered to sell hard to get .380 made with all factory fresh parts, including new brass to people who turn their noses up at it. At the same time I have had people try to buy ammo from me but think I should spend hours crafting match grade ammo and then sell it to them for less than what the components cost me.
Good luck and dump that old stuff that looks like crap. Surplus ammo is surplus for a reason. I know some of it is OK but I have just seen too much of it be crap.
