ballistic programs??????

[shotgunjoe]

Having used the Sierra program for a couple of years now I can say that it is close but not perfect. 7mm mag.,264 mag., .308 win, 223 rem and other calibers. At 1000 yds. it is usually within 1 moa but there will be variations at other ranges.

I have been using the precision shooters workbench from field firing solutions.

Have had great success with it out to 1200 yds so far.
