I have a .300 RUM Sendero SF-II. Factory barrel with a break & 3lb trigger. Am looking for your favorite loads with factory Remington barrels. I will probably be using 180 and 200 grain accubonds as they seem to be favorites here. Also please advise your case trim length and cartridge overall length. I searched for some loads on here, some of the links don't work any more. Found some loads listed but need some suggestions on seating depth.
