I would like to know what the minimum speed I should be at to shoot at a game animal? I have drop charts with speed so trying to figure out my maximum shooting distance. I called Beger and left a voice mail. While waiting for the return call I called back for a few hours and finally got through. I asked the gentleman, he said 1,400fps min. Then went on to ask me caliber, my fps, elevation, humidity, etc.... I tried to tell him this was all irrelevant and all I wanted was the min. fps. for a .308 168grn VLD. After all this he then told me 1,639fps then 1,000 ft lbs (maybe this means 168grn @ 1,639fps = 1,000'lbs?) So I am now more confused??? A day later a different gentleman returns voice mail and leaves me a message stating the min. fps is now 1,800fps min. for game hunting. Can anybody give me a straight answer? I hate to call back and get a different answer once again. This hunt I'll be hunting Mule Deer in AZ, but will use this gun from anything between Coues deer to Elk. Trying to determine what my maximum effective killing distance should be?
