In my warped mind I'm seeing a triangle. The corners are accurate, clean, and cheap. There might be a little middle ground, but I've not found anything recently that covers all those bases.
Worse, I've been burned a few times in the distant past, so I stopped assuming stuff. Back in the mid 1960s, I plunked down some of my summer earnings and purchased a Browning Tbolt. The guy at the gun shop where I got it took pity upon me. He'd been watching me enter his shop for weeks on end, never buying anything, but always looking longingly at the T2. When I had enough saved up (skimmed, really, because my parents thought I should be saving for college) I made the purchase. The old guy tossed in a 2nd can of Browning oil and a box of every brand of 22 ammo he could lay his hands on quickly. That was my discount. His advice was to go shooting and see what worked best for me.
It was good advice, and the winner of the competition was pretty unlikely. It was Remington golden bullet hollow points. No reason for that, except the gun just liked it. Remember my skill or lack of it was a factor. So I bought in big. Well, as big as I could given my anemic funding levels. And surprise, I still have several boxes of it stashed in the vault.
As I got rich (its all relative) and could buy more to stock away, a funny thing started to happen. My prize rifle got dirty and my groups opened up significantly. Cleaning my gun wasn't much of a chore, I loved it. But the groups were. So I buckled down but no joy. So I rummaged around and found some of my earlier ammo. Clean and accurate.
What had taken place was the factory apparently had changed some stuff in the manufacturing process. Just like we learned in 2008, all change isn't necessarily for the better.
So over the years I settled into a buying routine, much like that used by the military or labs. You buy a sample, test it, then make your decision if the stuff is up to your standards. My system was pretty simple, it had to measure up to the early Remingtons, and it made me value the small and dwindling stock of my "standard" even more. I'd just go out and find a likely candidate, purchase a single box of it, or of several, then go shooting. If it was good enough, I went back and plunked down as much as I could afford, often a full case. The only way to insure consistency is to have the ammo be from the same case lot. And the only way to know is to test it.
Frequently enough over the last 40+ of playing the game, I've gone back to the same store where I bought the last batch, and then purchased a test box. And it wasn't nearly as clean or accurate as the stuff I'd been using.
But now that I've rambled this long I realize there is now a 4th consideration. Its not just clean, cheap and accurate I value. Its also got to go bang when the rim is struck. If I have even a single misfire or dud in a box of 22s, I consider the ammo to be unsatisfactory for my purposes.
