Due to the packaging and shipping process, case necks are often slightly dinged or bent and need to be rounded up and sized to give proper neck tension. New and/or fired cases must be full-length resized or have the expander ball of the sizing die run through the case neck prior to loading.

Product Information

All Peterson Cartridge casings come in one of their plastic ammo boxes.

Made in the U.S.A.

2021 New Addition of 6.5-300 Weatherby to its growing family of rifle casing calibers.

Many people remember Roy Weatherby as the high priest of high velocity. He created new calibers that were the fastest on the market. Toward that end, he made a number of modifications to the traditional belted magnum casings of the day to achieve that goal.  

However, according to Derek Peterson, the president and lead caliber developer at Peterson Cartridge, “I suspect that some of the adaptations Roy Weatherby made were simply to cause his casings to be more difficult for his competitors to manufacture. And to that end Roy was successful – really successful.”

Peterson continued, “Over the years, in addition to creating tool packs for traditional bottlenecked calibers, PCC has also created tool packs for calibers that are rimmed and others that are belted. We’ve created tool packs for calibers that have a rebated head. Each of those different features produce their own challenges for caliber design engineers, and manufacturing engineers. But the bundle of different features Roy incorporated into his Weatherby calibers had us up against our ceiling of skill and knowledge.

  • The belt is different than the belt of other belted magnums.
  • Producing the double radius shoulder proved to be a real brain teaser.
  • And most of the tolerances are half of those of other belted magnums. 

“But in the end, we solved each and every problem, and we are now producing 6.5-300 Wby casings, Peterson said. “We’ve run them through all our tests and quality checks; and believe them to be excellent 6.5-300s. This is the first of the Weatherby calibers we will be coming out with.”

 

Warning: Only use Peterson Cartridge Co. casings in firearms in good condition, designed, marked, and chambered for this cartridge. Do not use Peterson Cartridge Co casings for “fire forming” or any other purpose other than what they were designed and tested for. Peterson retains no responsibility for the enclosed casings if they are used outside of the manufacturer’s recommendations.
