I just got another e-mail regarding the limit on using a particular bullet at some stated velocity. This latest question was about using a 220 grain Sierra 30 cal at 3200 fps. The question was whether this would work on deer at 1500 yards. I'm sure we all get asked similar questions quite often. I feel that in a good broadside double-lung shot, nearly any bullet that can survive the trip through both lungs will kill the animal. (There are limit of course, perhaps a monolithic 14cal. at 800 fps would be a poor choice.) The, "what if" crowd, nearly always want's a premium hunting bullet just in case the animal makes a quick "left face" and we end up striking the unfortunate critter in the bum. My line of thinking on that is that I didn't spend enough time studying the critter before the shot so it's not a bullet problem but a shooter problem. What are your thoughts on minimum energy, bullet design (I sure we're nearly all of the same thinking here) and shot placement? For us 'first round hit' (no sighter shots)guys, how about the trajectory limitations. Specifically, how do you determine at what point the trajectory angle gets too steep, steep enough for a miss due to a marginal distance error (+- 10 yards or so).
