In my 209x50 Omega which has the same barrel as the prohunter I was able to get a ragged hole with the 223gr areo tip and 110 gr. RS . It may take about 40 shots to break in the barrel . The rest of my loads would be no good were you are . Take some time to get used to the new gun , they are great I have 3 barrles for my Encore .
