Re: 6.5 140 smk
Very different ogives and a somewhat modified boat tail, as I recall. In short, two distinctly different bullets, and the 142s are vastly superior in terms of BC. Sierra needed to do something to counter the Berger, JLK and custom 6.5s that were eating into that market,and the 142 was the result. The 140s should do okay for deer, but just be advised, these aren't really designed as hunting bullets.
