I bought a 338wm pro hunter barrel last year, for a back up to my sendero 300rum , for last years elk hunt. Didn't have long to play before I left and with the first scope being bad, cut my time down more. Here are my results.
All groups were shot at 100 yds.
Fed speer hotcores 225gr. 1.5'' groups
Fed noslor Accubond 225gr 2''groups
Fed nos. part. 210gr. 3'' groups.
Although not bad, not what I was expecting with all my other PH barrels shooting much better. Have not messed with since. Will try a few things to see if I can get it a little better. Will probally stay with the 225 accubonds. Have others for 200gr and under. If I can't make the fac. shoot with then I will go to the bench.This barrel will most likely only be used for elk or hopfully an Alasken bear hunt. If I can get to MOA I will be satisfied. Will still use the the 300rum for the long work as my last 2, 3 shot groups at 300yards were 1 1/4 c2c. This is with handloaded 200accubonds over 92.5gr RL25.
Hope this helps, DM
