WL.........Sierras are a very vanilla cup and core bullet, no bonding or partitioning or what have you. Therefore they work as one would expect when started around 27-2800 fps or less, however they fail abysmally when started over 3100 fps and are anybody's guess between 2700 and 3100 fps. I use them in my 7-08 Model 7 MS carbine and like SLH said they shoot like match bullets. If I have an accuracy problem with a new rifle after trying 3 or 4 bullets and several powders, I will go and buy a box of Sierra boattails for this caliber in the optimum weight range and try these. They are my "go to" litmus paper constant to tell me if a rifle will or will not shoot well.
Because I generally hunt with cartridges producing 3200 fps or more I do not use Sierras for my hunting needs, pretty much all Accubonds, Partitions, A-frames, TSX and Matrix (hopefully will still be able to get some more in the future). All of these bullets have proven themselves to me in the field on game, of various sizes and at various distances.
