New seekins barrel technology

[stan_wa]

This video explains what they claim is new barrel tech.

Harder steel
Gain twist
Different less sharp rifling style

Seems to me it’s all to bias towards these new high pressure loads. I don’t think any of this stuff is really new. I know Hornady podcast said gain twist does generally help 10-15% with dispersion. I like the idea that you can run a little hotter load and get more mv with less of a pressure spike.

I respect that seekins is gonna open source the design details for others. That’s cool.
What’s y’all’s take is there anything cool here or just marking

Thread 'Thoughts on new Seekins barrel tech?'

Mar 20, 2026

Looks like Seekins is going to be releasing some new barrels to address higher pressure cartridges. They claim that using a high gain twist and sinusoidal (think sin waves) lands and grooves will give longer barrel life. They also say this will be available for all cartridges, not just the new high pressure ones, and it will increase barrel life on any cartridge.

I'm not exactly itching to use the new higher pressure rounds, but will this actually increase the barrel life on any other cartridge (thinking 6UM)? Or is this just more marketing fluff?
