Thoughts on new Seekins barrel tech?

[pattimusprime22]

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?

Sounds like some similar approaches as the new ECM barrels that McGowen/Carbon six are making. Wonder if they are working together..

I think N570 burns throats by heat a whole lot more than by pressure in my barrels.

Heat mitigation is part of that design from my understanding.

The guy with Glenn needs to shut up and let Glenn talk.

This is eerily similar to Proof Reaearch's new PXT barrel technology. You can find the trademarks they filed for it in May 2025. I wonder if they have an agreement with them to use it. The way Glenn talks about it, he makes it sound like he came up with it.

I’m not sure but several companies besides proof and Seekins doing this. If I remember correctly I thought CarbonSix was doing something similar as well.

A trademark on a name and a patent on a process are wildly different things.

gonna be as gamechanging as carbon fiber barrels, no doubt about it

Rifling gain has been around for awhile and is all well and good tech for increasing velocity, limiting deformation of the bullet, and decreasing copper fouling... but what does it have to do with barrel life!?

I'm no expert, but barrels wear out by burning out the lead into the rifling at the throat, right? This occurs from powder abrasion (significantly higher in magnum rounds because actual powder grains are traveling into the throat), heat, and repeated shots while the throat is hot (the throat can erode in a few hundred shots on a full auto for this reason).

All the significant barrel wear occurs before the rifling really has an opportunity to start, right?

Better order the perfect barrel length the first time. No chopping that sucker down once it’s done.

That would be my thought as well. Gain twist has been around for a long time but not as dramatic as what was described in that video.

Maybe the bullet and associated pressure of immediately engraving into the lands of an 8tw vs 100tw has some effect to help reduce wear?
