[QUOTE="GBA1776, post: 387994, member: 20522"] WOW what an awesome test and very interesting i also shoot a mixed bag of ammo whatever i can get/ price usually Aguila supermax 30 gr American Eagle 40 gr or Remington Viper 36 gr when i finish typing this out i wil mic. out all of the rims to see what sort of improvement i can get by doing that. thanks for taking the time to do that and then post up your results. I am currently compiling a list of of 22lr and 22Wmr ballistics muzzle Energy/velocity then at 50 yds and at 100 i also am measuring ballistic coefficient using a sample of ten rounds per box but scince i cant get my hands on all types of ammo im afraid that list wont get completed. The .22WMR list is done with quite a few of the B.C's measured if anyone is interested let me know and i will post it up i have it in wordpad and for those who want it in Exel format and here is the link for the ballistic coefficient calculator i use [url=http://www.uslink.com/~tom1/calcbc/calcbc.htm]Precision Ballistic Coefficient Estimator[/url] its at the bottom of the page. So if anyone wants to make there own measurements and get real B.C. data you can you will need a micrometer to do so, but you can get one for about $25 at an auto parts store. or just take about %30 percent off of the manufacturers B/C data and you will be pretty close from what i have found [/QUOTE]
