Re: Need Advice on Caliber
[ QUOTE ]
Hey, check this: After a decade of no guns at all, I get back to one of my old pursuits. I set a target at some arbitrary range, do the ballistic calculations for range and atmospheric conditions, and take one shot. Now with my new Nikon laser rangefinder (!) and ballistics software on my PDA (!!) I set my water jugs out in the field at 500+ yards, make my measurements, calculations, click-click-click -- BAM----splash. That blows me away, never was able to do that before. So don't be disparagin' the ol' calculator to me

If you feed a calculator accurate data it will do amazing things. In that sense you are correct. If you hadnt previously tested your load and figured out the actual BC and not the published BC then you were none other than lucky. Take for instance the 178 AMAX fired at 2550 FPS and the same bullet fired at 3100+ the BC for both senarieos is WAY off the published BC. If you plugged in the published BC and took those numbers to the range you would miss a 4' target. That said you cannot base a caliber choice on calculations. Imagine plugging in the published BC for the 178 AMAX and comparing it to a poular 7mm rem mag load, the calculator would tell you the 7mm would blow the doors off the 300 RUM when in reality, in the "real world" the 300 RUM would leave the 7mm rem mag in the dust with the 178 AMAX. The 308 is the same way there are bullets available that will give a 7-08 a SERIOUS run for its money, despite the fact that "on paper" the 7-08 blows the 308's doors off.

Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
