i have made a few conclusions regarding the .22rl ammo testing. first, i find that hollow point .22 ammo does not make any noticeable difference on its own. dont flame me, these tests were not scientific, and im not an ammo expert. the tests i totally made up, and the data i collected was by observation and notes only. hollow points did not make or break the results, most times there was little to no mushrooming of the hp, except into a gallon or more of water at 25 yards or so. however i did find that the heavier grain bullets hit harder ( measured by penetration and movement of steel plate ). remington bulk ammo had alot of squib loads no matter the model of ammo. the fit, finsh and cost, all were looked at, availability and range of styles and weights.
having said all that, i personally favor...wait for it .... CCI's. they are consistant, fairly priced ( for hunting , not plinking ammo ) effective and have a wide range of options.
these are my personal observations and opinions only, im not endorsing any brand.
higher velocity rounds are more accurate, hit harder and seem to work best for me. i dont think hp's matter, with such a small surface opening, the fluid dynamics that hp's need to work upon, are there, just in too small a size to make a real difference. some of the brands opening were only a few thou' accross.
i feel its better to go with the heavist grain bullet you can get, like 40 grains or so at the highest velocity you can find 2000 fps. ideally. im not sure just how large of an animal this will take. thats where the field time comes in. and this setup may be to much for squirrels at closer ranges too. the limiting factor there is a head shot.
my tests were limited to 100 rounds of the ammos i tested and im sure i did not test all possible makes. just what was available locally to me.
the aguilas are great rounds, well make and reliable, but hard to come by in most styles. they preformed as well as CCI's, better then the larger brands.and they make a style that has no gunpowder in them, low weight and muzzle veloity, but they have little to no report when you fire them, they sound like a pellet gun.
good for indoor practice, or hunting sparrows and rats, not sure of their killing power on anything bigger.
i'll report more when i kill some game animals..
