[QUOTE="Fiftydriver, post: 588677, member: 10"] I have found that the Hornady 285 gr produces very similiar velocity to the 300 gr SMK inspite of its lighter weight. Main reason for this I believe is because the baring surface of the two are very similiar which result in similiar velocity potential. It seems BC is slightly higher then their listed .720 but not much. I do not see much advantage going with that bullet over the 300 gr SMK but it is an accurate bullet and shoots well so its another viable long range choice. Just not a huge advantage over the old standby. The 300 gr Berger Gen 2 is bullet with much higher BC. It also has a significantly smaller baring surface then the Hornady or SMK so velocity potential tends to run a bit higher. BC is certainly higher, easily in the .820 range in my ballistic testing out to 1200 yards or so going off bullet drop numbers. IT has been interesting to see that out of my 338 Allen Xpress loaded to around 3000 fps, I had to use .840 for a BC but out of my 338 Allen Magnum loaded to 3380 fps, BC was much closer to .810 to get trajectory to match up over 1200 yards. Most likely this is because I am using a 1-10 twist and with the near 3400 fps velocity, its just way more RPMs then needed for this bullet. A 1-11 would likely be a much better choice for this bullet. I have also been extremely impressed with the 265 gr TTSX which I think they label as the LRX or something like that. BC is in the .650 range, not great compared to the match bullets but it can be drive to very high speeds. Testing in my 338 Allen Magnum I was driving it to 3550 fps easily with comfortable loads and expansion was good from 500 to 1500 yards and to my surpise, it shot to nearly the same point of aim as my 300 gr SMK load out to 1500 yards in the Allen Magnum. I do not know how expansion at long range would be with lesser chamberings but I was impressed with it in my Allen Magnum. The new 300 gr Nosler Accubond may also be a great all around choice if it actually does reach its .720 BC. So far, Nosler has been pretty good with BC predictions, I hope they are in this case as well but it would be a HUGE jump over their 250 gr version. [/QUOTE]
