Yeah, I pulled and retorqued the action, the scope doesn’t seem to be the issue because the factory loads are shooting the same consistent group from start to now. Haven’t tried a new die set but that’s an option. I was hoping someone on here had a Howa 300 and could give me some direction.I would, in this order:
1) Remove the action, look for binding points, reinstall and torque correctly
2) Try a different scope to see if it is part of the equation
3) Try a different die set
4) If all these fail I'd look for a different bullet/powder combo
If it shot them like that, I would buy a case and be done....I'm spoiled with my other rifles that shoot 3/4 MOA all day long.Eastcoaster, I too have a .300 Win Mag that will only shoot the "cheap" Winchester Powerpoints (a 1960's Remington 700 BDL). While that stuff is not the super-cool sexy ammo available today, it shoots three rounds in one hole at 100 yards, when I do my part. I have taken elk, caribou and whitetails with those 180 gr. cheapies.
Sounds like that is the best option and your on the right track. It will be interesting to read about the outcome.Thank you everyone for the help. I talk to howa and they told me to purchase a specific horandy load. Went to the range with said load and it shot 2) 2" groups and stuck a case in the chamber on the last round. I called them back and they were very helpful starting the warranty process. I'll keep you updated incase anyone else ends up in this situation.
