It isn't always about what you're doing and about what you're buying.
About a year or so I had the displeasure of buying about 10000 or so Remington small pistol primers. The were dirt cheap, $19/1000.
Turned out, they were good for malfunction drills and aggravation. They had a 5% plus failure rate, and most did not fire on the second strike.
I loaded them in 9mm (most of what I shoot handgun wise), 38, and 357, and all had the same problem.
They do work great for unstaged, and unexpected malfunctions though. That was the only good thing about them.
I normally use CCI's for pistol and rifle, unless they are unavailable. Never had an issue with them. They are all I use in my rifles, as I've had slam fires with Winchesters in my AR's.
The CCI's seem better suited for rifles where that is, or might be an issue.
Ive been using an old RCBS "O" press to do my priming. I tried the hand presses for awhile, and was not having good luck with some of the swaged military cases I was using at the time. Even when swaged, they were often still very stiff, if not impossible to get seated with the hand primer. The press gives a lot more leverage to get things done.
I can "feel" the primers seat fine, and every round gets the finger test as it comes out of the shell holder.
