Federal has taken the high-pressure case technology first seen in the 7mm Backcountry and applied it to the 6.5 Creedmoor, creating the new 6.5 Creedmoor +Peak. This new ammunition promises to deliver 6.5 PRC level performance out of a standard 6.5 Creedmoor rifle. In this episode, Outdoor Life shooting editor John Snow returns to the podcast to discuss his extensive pre-launch testing of this groundbreaking ammunition from Federal. We cover real-world performance with this ammunition in 20″ and 24″ barrels, how that performance compares to traditional 6.5 Creedmoor and 6.5 PRC factory ammunition, what reliability was like, and the exciting news that these cases are reloadable. We also dive deep into Proof Research's revolutionary PXT radical gain-twist barrels and why they're a perfect match for higher-pressure loads, including major improvements in barrel life. We also discuss potential +P versions of other cartridges (like the .308 Winchester and 5.56 NATO, etc.), implications for suppressors and short-barreled rifles, military applications, and how this technology is resetting expectations for centerfire rifle performance.

The Only 3 Cartridges You Actually Need for Hunting

5 Forgotten Classic Cartridges Making A Comeback In 2026

In this episode, John McAdams sits down with Tyler Grethen, Marketing Director at Weatherby, for a comprehensive look at one of America's most storied firearm manufacturers. Tyler shares the fascinating history of Roy Weatherby — from door-to-door insurance salesman and garage tinkerer to creator of some of the fastest production cartridges ever made. They discuss the move from California to Wyoming, the legendary Mark V action (including the nine-lug, six-lug, and new short actions), the extremely popular Vanguard line, the innovative 307 series built on a Remington 700 footprint, as well as Weatherby's cartridge lineup and their loaded ammunition offerings.
