Okay. But, personally, I haven't found website or the published literature to be particularly accurate. If you're really interested in this sort of thing you need to take the time and dollar$$$ to purchase several different types of ammo and a Chronograph and then shoot the stuff through "Your" gun. In the end, it's the only one that matters. You might also want to invest in some additional testing materials to decide for yourself. Same goes for reloading. You need to do the 'testing' in your gun.
Personally, I've been shooting for something over 50 years now and I've done my fair share of testing and I've even managed to blow up a few guns in the process but that was done on "Uncles' Nickel" and not out of my own pocket. One of the most important things I've learned is it doesn't make any difference what you shoot somebody with but "Where" you shoot them.
My Father-in-Law survived to be 81 and took three hits from a .50BMG in his chest during WW-2 and did his "recovery" in a German Concentration Camp! All the odds were against him and yet he managed to recover, escape and crossed the North Sea in the middle of Winter in an open boat to boot. He lost a lung but not his life or his will to live.
By the way, I have yet to find a good quality gun that wasn't more accurate than the person shooting it. So, if you're going to be testing for accuracy you need to do as much as you can to take the "you" out of the 'equation' and this means using a good set of sand bags or a Machine Rest. Bags are cheaper but will only go so far.
Practice, practice and then practice some more. And, yes, you do need to shoot with the gun and ammo you plan on carrying but "plinking" with a .22 will do nothing but improve your shooting skills as long as you shoot every gun and every shoot; remembering the basics of Sight Picture and Trigger Squeeze. You can learn to Point Shoot and do much better than you ever thought you could but that will likely take some good instruction from a could teacher.
