[QUOTE="SSG Graybush, post: 2629490, member: 115190"] My 300 wm with a max load of 78 grs of H1000 pushes a 208 amax at 2882 fps, 26" barrel. It shoots very well at 1000 yards. At 1000 yards it has about 1270 #'s of energy, compared to a 308 with a 185 jug starting at say 2664 fps which would have about 750 #'s of energy. In a 3 to 8 mph fv variable wind the 308 would drift between .6 and 1.7 mils, the 300 wm drifts .4 to 1.3 mils. So you can split the difference and get a hit on a regular sized 18 inch wide silhouette with the 300 wm, you can not with a 308. In any caliber its the same. A 6.5 Grendel shooting a 123 gr .51 g1 bc bullet at 2500 fps is hard to get consistent hits at 1000 in the same wind, compared to a 6.5 cm shooting a 147 gr .629 g1 bc bullet at 2650 fps. I use this analogy cuz Ive seen it numerous times at my range. Better bc coupled with slightly more speed reduces the margin of error. Whether its holdoff or even vertical dispersion. Am not hating on the 308. Its pretty good enough for hunting within distances most shots are taken. But for long range, its lacking. 3006 is a good round. But imo a .6+ g1 bc bullet going over 2850 fps is the standard for any long range round, in any caliber. Especially for hunting where moa or better accuracy is needed to be ethical at distance.
