With a good barrel I have not found the 6.5 caliber medium sized rounds finicky at all. I have limited experience with cartridges .264 magnum and above so these may be a different story. Loaded several 129-130 grain bullets in my 6.5x55 Forbes rifle and they all did well. Ended up hunting with the 129 Hornadays and Nosler ABLR.

Another nice thing about these well rounded cartridges is I can shoot multiple bullets in this range with no sight changes.

I even had good accuracy from bargain PPU bullets, they were not that far behind the Berger 130s.
