Steve at Hammer Bullets said the oil will not cause any problems so do not concern your self. I will be going on my first safari with the Hammer boys in April so we will be talking a lot about 458 bullets and later this year I will be working with the 400 and 450 loads, to cold now, the other day Brian told e there was a guy up in Alaska going to be testing on a brown bear so will be interesting to see what happens.next year I will go back and tackle a cape buffalo with Hammers. the trip we are taking in April will only be shot with Hammers for plains game. good shooting
