[QUOTE="Michael Eichele, post: 251368, member: 1007"] The sierra 240 MK sports a BC of .711 and is an awesome bullet but a wee bit too big to make it practical for the 308 winnie. Some guys do use it though for the extreemly long paper or gong pokes. It will carry much farther than just about anything. The 168 is a great mid range target bullet capable of amazing accuracy but wasnt designed for 1K shooting. The real world experiances of myself and countless others selidify sierra's claims that it is not intended for 1K shooting. The 155 sierra palma bullet is specifecly desined for the 308 and 1K shooting as is the 175 SMK. Both do amazingly well both for accuracy and good BC's. The 190 was never desined for the 308 but works quite well. The 155 SCENAR with a BC of .508 at velocities around 3000 is about the best you can do for a match load "on paper". The results in standard air are: 1000 yards Velocity = 1455 Energy = 729 Drop = 253" Wind (10 MPH) = 73" 260 139 SCENAR 1000 yards Velocity = 1569 Energy = 760 Drop = 250 Wind (10 MPH) = 61" My point is and always is that the 260 maybe "better" perfoming than the 308 but hardly "blows the 308 out of the water". The 308 is still plenty capable and is more than capable of holding its own. Factor in the fact that you can go to the range much more often and actually get to know your rifle instead of worring about the round count never hurt anything either. That was from a "match" standpoint. Now lets compare practical hunting senarios. Elk at 600 yards. 308 with 180 AB. Velocity = 1751 Energy = 1225 Drop = 64" Wind (10 MPH) = 26" 260 with 140 AB Velocity = 1817 Energy = 1026 Drop = 59" Wind (10 MPH) = 26" Which bullet do want in the shoulder? If I had to shoot an elk at 600 yards I would rather havethe same inches of wind drift and a few more inches of drop AND a 7.62mm 180 ACCUBOND heading for the shoulder than a 6.5mm 140 grain ACCUBOND.
