I guess it depends on the bc of the bullet. The heavier bullet has to be a pretty significant step up in BC over the lighter to over come the velocity loss. In my 6.5 CM, I can get enough velocity out of the 150 smk to make it worth my while over the 140s. The 147 eld wasnt worth it in my opinion. Like wise as I'm finding with the 130 eld and the 140 eld. I can push the 130 eld fast enough to just about match the same wind drift as the 140 eld. You just have to get out and test for yourself to see what works for you.
