Here are my thoughts on the entire Creedmoor family: the 22 Creedmoor, the 6mm Creedmoor, the 25 Creedmoor and the 6.5 Creedmoor. We'll discuss how they stack up next to each other on paper, how they perform afield on game, and what the ideal use cases are for each one. I'll also share my picks for the "Best Creedmoor" and the "Worst Creedmoor".

Richard Mann is back on the show and we discuss a subject I know you'll enjoy: our favorite cartridges for hunting virtually any species of big game. We're play little game where Richard and I each list our favorite cartridge and bullet for hunting specific species of game ranging from coues whitetail all the way up to thick skinned species of African game like cape buffalo and elephant and almost everything in between like mule deer, elk, black bear, etc. The catch is we cannot reuse a cartridge for multiple species. Even so, our discussion provides an interesting glimpse into the thought process he and I each use for selecting cartridges and bullets for hunting different species of game.

Today, Rob Massa from the Bergara Academy and the R&K Hunting Company in Wyoming joins me on the show to discuss some observations he has made on what cartridges and bullets work and don't work from over 20 years outfitting elk hunts in Wyoming. I first met Rob while attending an event at the Bergara long range shooting Academy in 2024 and I was incredibly impressed both with his knowledge of shooting and hunting as well with the professionalism he ran the Bergara Academy and the R&K Hunting Company with. With that in mind, I decided to bring him on the show to discuss some insights he has developed over the course of over 20 years in this business on effective elk hunting cartridges and bullets. Sponsor: Get in touch with Rob at The R&K Hunting Company In Wyoming to book an elk, antelope, or deer hunt. I cannot recommend them highly enough: they have hardworking and friendly guides, comfortable lodging, great food, and fantastic hunting. Plus, they can also help you get a tag with little or no points for those species. Visit their web site or call Rob at (435) 979-1497 to learn more. Email me john@thebiggamehuntingblog.com if you're interested in joining me on the Big Game Hunting Podcast antelope hunt 9-14 October 2026 in Wyoming. In this episode of The Big Game Hunting Podcast , host John McAdams sits down with elk outfitter Rob Massa to discuss his favorite cartridges and bullets for hunting elk. Rob shares a few stories of effective terminal performance on elk, how tough elk are to kill, his favorite shot placement on elk, how things have changed with the most popular cartridges and bullets for elk hunting over the course of his career, and much more. His takeaway? There are lots of things that will work on elk, but certain cartridges and bullets tend to deliver a mix of performance that delivers the best overall performance.
