The Barrel Maker Who Won’t Quit Learning: Mike Johnson

I’ve known Mike for years, and I’ve watched him go from a one-man shop with a lathe and a mill to running one of the most interesting barrel operations in the game. It’s been 3-5 years since he was on the podcast, so we start with the big picture of what HCA looks like now and then get deep. We talk about the business side first: doubling the team, tripling the shop space, and why the best business ideas are the ones you can’t talk yourself out of. We also get into why a decade of relationships is worth more than any piece of equipment, and why helping your “competitors” has paid off for both of us. Then it gets nerdy. Mike breaks down the four ways to rifle a barrel (button, cold hammer forged, cut, and ECM) and why he went the route he did. We cover what separates a premium barrel from everything else, why you can’t scale craftsmanship without losing something, and the electrochemical machining process he’s been learning the hard way. Then the big reveal: **HC1 rifling**, a new gain-twist and gain-land design that Mike says is the most forgiving barrel he’s ever shot. He walks through the testing, including what happened when he pushed a 22 Creedmoor well past where it should have quit. We finish with barrel maintenance, barrel length, suppressors, and a few elk hunting stories along the way. Mike also tells me how to get your hands on one, and now I need a new rifle. I blame him. * * * ### Sponsors **Maven Optics** Maven is a Wyoming company that sells direct to consumer, and in my opinion they’re the best bang for your buck in optics. From rifle scopes to spotting scopes to binos, I love their stuff. The B6 is my go-to binocular. I run the 12×50, but the 10×42 is awesome too. !🔗 mavenbuilt.com | Code: **TRO** **onX Maps** onX isn’t just for mapping. It’s my planning tool, my e-scouting tool, and my offline maps for every trip. Now they’ve added **onX SOS**, an emergency rescue add-on that connects you to Overwatch Rescue for 24/7 crisis response right from your phone. I carry my InReach a lot less these days, and having this insurance on my phone is a big deal. !🔗 onxmaps.com | Code: **TRO** **Bridger Watch** I’ve spent the last three years developing the Bridger smartwatch, the one I wished existed. It does health, sleep, and fitness tracking, plus hunting features like offline mapping, onX waypoint integration, ballistics integration with Hornady or Sierra, and Redshift, a red-light mode that protects your night vision. The Rekken is built by hunters, for hunters. !🔗 bridgerwatch.com | Code: **TRO** * * * ### Chapters - **00:00** Sponsor reads: Maven Optics and onX SOS - **01:45** Catching up with Mike - **03:00** What’s new at HCA: doubling staff and tripling the shop - **08:00** Finding problems to solve, and what you say no to - **13:00** Advice for your younger self: patience and readiness - **16:30** Why a decade of relationships matters - **21:30** Sharing knowledge with competitors (and East Coast vs. West Coast) - **27:00** The road to making barrels in-house - **29:30** Four ways to rifle a barrel: button, hammer forged, cut - **36:00** The art of a premium barrel and the scaling problem - **39:30** ECM rifling explained - **44:00** Bridger Watch (mid-roll) - **45:00** HC1 rifling: how gain twist and gain land work - **55:00** Barrel maintenance - **58:00** Barrel length and elk hunting stories - **64:00** Suppressors and big 30s - **67:00** Gold flake barrels, HC1 pricing, and steel barrels - **70:00** Where to buy, pre-fits, and wrap-up * * * ### Three Key Takeaways 1. **Your relationships are your biggest asset.** Both of us say the same thing: the opportunities that mattered most came from a decade of relationships, not overnight moves. Mike could only start making barrels because people he’d known for 10+ years mentored him. 2. **Sharing knowledge grows the pie.** Mike used to guard his carbon wrap process and thinks it slowed his growth. Helping competitors and contract partners has brought more back to HCA than it has cost. 3. **Barrels still need a human.** Even with ECM rifling and a scalable process, Mike insists every barrel gets hand-lapped and checked by a person, because automation alone doesn’t make the best product.
