Here is some pics of the 250 grain Hornday and 300 SMK
Top is the 300 SMK and below is the New Hornady, note the smaller hollow point.
In this photo you can see how the 300 SMK on right has a hollow point that is squared off, while the 250 grain Hornady has its hollow point rounded off and the tip closed in quite a bit.
The boat tail of the Hornady also looks a tad longer than the SMK.
I have not shot the 250 grain Hornady but plan to when the weather cools down a bit, it is going to be about 40 degrees C here this week in Victoria.
Plus a man has to work some time!
