[QUOTE="nralifer, post: 2696068, member: 94556"] I have been using for years the 150 BD and BD2 bullets with MVs of 2920 from a 20”barrel and 3050 from a 24” barrel using Leverevolution which outperforms most 3006 loads. Have killed African Plains Game and a large Alaskan Coastal Black Bear all with single shot DRT kills. The attachment is a JBM trajectory calculation of our 175 gr BD2 bullet propelled from a 24” barrel which I think is entirely achievable for the 308 Win at 4500 ft elevation, which is not an unusual elevation to hunt Elk. The higher you go the better. At 900 yds that bullet still has 1300 ft# of energy snd is traveling at 1836 fps which is at least 100 fps more than is required to get it to expand. What makes this possible, and it is the point of the thread, is using a bullet with a high enough BC that will expand reliably at 1700 fps impact. That has already been done by a friend of mine using our 195 gr bullet with a higher BC from a 300WM at 1225 yds. [/QUOTE]
