I am fairly new to serious shooting. This is to say im 34 years old and have been hunting and shooting in one fashion or another since arround 7 when I got my first bb gun. I have within the last 5 years just come to understand how little I knew about the science of shooting. It all started when i purchased a FN pbr in .308. It has a 24 Inch Barrel with a 1/12 rh twist. After picking up the rifle I was intrested in seeing what it could do, having taken almost all my game with either an old .243 or a bow I had really never shot a accurate rifle. So I grabed my single stage press, a reloading manuel, a box of bullets and a small selection of powder, and began what would turn into 5 years of the most mind racking confusion one had ever experanced. I will not get into all the steps that lead me here but long story short I happened (for lack of better term) upon some decent advice and found a winning combo for MY rifle. Currently I run the following: Hornady A-Max 168gr. 46.2gr Varget Federal 210 Primers Federal Champion Case COAL- 1.282 AT 2985 +/- 18 fps Now for the big question, What is the deal with 3500 FPS. I have seen all sorts of advertisment for 300rum, 30-378, 300 win mag, etc. and from what I can tell each run a .30 cal bullet at arround 3500 fps well respectitavitly starting at 3220 for the 300 WSm and ending up at almost 3500 for the 30-378. Now before we get into it I do understand BAC and flight time and bigger faster is better, but that being said the above fps readings are all from 168 gr bullets. The problem is that I can shoot my .308 all day long with little fatigue at arround 3000fps but when i nuzzle up to my friends 30-378 it is flat punishing. Not to mention he runs arround 110 grains of powder to boot. All of this to grab 480 fps. Is it worth it, does 480fps really make that large a differance? Or are we throwing good money trying to reinvent the .30 cal wheel? Sorry for the long story to get to a point just thought a little back ground would be appreciated by educated readers. Thanks for your support.
