atkinson6, If I shoot the 300 gr bullet in my 338 I would only be able to get 2750 fps with those 300gr bullets. What I would like to know is if these 250 gr R.N.bullets hold up at 2900fps to 3000fps and over. So I have written a letter to Hornady about this. I was thinking about loading some at those fps. I don't know if I would use them for hunting or not, it's all what Hornady says.
