I have a box of the 155 berger hybrids and 155 sierra matchking palmas I am going to try out in my 10" twist 24" barreled gun. I want to see if running the lighter bullets a bit faster at the less than 600 yards will be better.
Twist rate should will be fine. Although I would choose the hybrids over the fullbores. To get the fullbores to group well from my rifle, I had to load them beyond mag length. So unless you are shooting a single shot I would buy hybrids.
