I don't have any experience with them, sorry.. My curiosity is "why" would you consider them when there are lots of great 150-160 and even 130-140 grain bullets with proven back grounds.
I have a box of the Speer 170 gr rn .270 bullets and just haven't seen a need to load them...
My last years bull, a 5x5 Roosevelts took two 150 Core Lokts that were pass throughs. They worked perfectly.
Unless you already have some Woodleighs handy or a cheap sourse, I doubt they're worth the effort.... My humble $.02
