Just going off of what the ad on Norma's website shows, it looks very similar to the woodleigh of similar weight with the possibilty that the woodleigh might be a little heavier built, but that is something I don't know. They don't show a cutaway and without looking at the structure of the bullet it is hard to say how tough they are. It says the jacket is soft (I assume annealed) gilding metal built for "rapid expansion".... I would say get some and give them a try!Just picked up a couple of boxes of the 286 grain Norma Alaska bullet to try in my 9.3 x 62. What can you tell me about them? What are they similar to?
