Excellent Article:Testing .22 ammo velocity/accuracy
Worth the read:
I had two goals, besides the obvious one of spending a day trying to wear out the Marlins barrel. I wanted a look at the velocity numbers of (16) various makes of .22 ammo, and I wanted to pin down what the Marlin shoots best.
As a side bar, I was very curious if velocity consistency is a key to rim fire accuracy, as it is in a center fire. With my heavy barrel varmint rifle I look for less than 20 fps variation shot to shot. This tells me I have a load with consistent internal ballistics. I expect the same from any match ammunition I load, including pistol rounds....
I'd have liked to have seen the Standard Deviation for each test, not just extreme spread. But this test was done over two years ago and the data itself wasn't published (which would have let us do it).
Interesting, but as he concluded, every rifle is going to be different and marlin doesn't seem to have much in common with the 15-22. Even comparing 15-22s there seems to be wide variances in what works for some and others
