They are exactly the same bullet that Norma´s partner company, RWS, markets with the name Evo Green.
I have used them extensively in my 7x57R with a muzzle speed of 3,050 fps for culling mouflon ewes in my country and black and blue wildebeest in South Africa.
The front part fragments upon impact scattering the fragments as secondary projectiles forward and in a radial fashion as I have been able to track when making the autopsies. The shank remains intact and penetrates like no other bullet I have ever tested. So much that it took
a few black wildebeest shot lengthwise to recover just two, the ones whose photo I attach.
They are not what you would call fast killers and everything that was not spined would run more than I like to see. In my opinion, the fragments it releases are too small, or the shank is unnecessarily large, which limits the amount of tissue they disrupt.
They are very accurate in my two Blaser K95s in 7x57R, shooting 5 shot groups in 0.7" at 109 yds (100 meters).
They work well, or at least like they are supposed to work, up to 400 yds or so. If loaded at 7x57 or 7-08 speeds I would not shoot them at anything at 500 yds or more.
Hope this helps but feel free to ask any questions,
