Name calling is not allowed on this forum ZZ so this will be my last response to you. I never no way said ME does not mean anything. I keep saying (which you never hear) That you can't say that one leg of what I would call the killing formula can do it all. Bullet weight means something as does SD ME MV and would channel and range and bullet design. You have pointed out all the stong points of the 243 many times. Well at 500 yards it falls 30-35 percent behind the 280 in ME. This because of velocity and bullet weight. 924 ME for the 243 and 1371 ME for the 280. This from nosler with BT bullets of 100 grains for the 243 and 150 grains for the 280. There is no magic pill. The heavier bullet in this case shows its strong points. I have tried to get this accross many times. Velocity can't do it all. The 100 grain bullet in some cases is the 243's strong point. On this leg of the formula it is its weak point. What the fast 100 grain bullet can do at 300 yards or so, it can't hope to do at 500 yards. It may be fast and low in recoil but get out at those ranges and it can't deliever the payload of a bullet half again as heavy. Keep the 243 in its place and its a fine round. It can't compete with many of the other rifles on your chart for long range big critters. It just does not have the material to do so. It is past its effective range for big game.
