Dont give up on the bullet yet. My Ruger m77 in 30-06 is a picky gun. Ive had a few loads where i had to run from the starting charge up to maximum in small increments until i hit a sweet spot and the groups shrunk dramatically. Ive had decent luck with H4350 powder. My buddy who is a 308 guy swears by varget. I will be trying that next. Ive had my best luck so far with hornady bullets h4350 powder and remington cases. My gun also likes quite a bit of jump as well. It doesnt like the bullet close to the lands.
