I'm going to use the 170 grain Power Point this year out of the 336. 1" groups at 50 yards, 2" at 100 so that's plenty accurate for the round. Heard good things about them. Have used Power Points with great success out of the 30-06 and .300 Win. in the past.

I have used 170 gr Rem hollow points and also the 170 gr corelokt, both worked very well for me. Many years I loaded a bunch of 150 gr Centrex (believe that is spelling) and dropped quite a few deer and many ground hogs.
