Thoughts on new Seekins barrel tech?

[nm.otter]

Potentially, yes -- hence the common practice of only adding a small amount of gain.

In this context, heat and pressure are locked together. Increase in pressure = increase in temps. As volume expands, pressure goes down and so does temperature. Gas temps inside the casing at ignition are about 5000F for a microsecond - and as soon as the bullet moves forward, temps start dropping rapidly. It's about 4000F an inch or so past the chamber, and about 1500-2000F by the time the bullet exits the muzzle, depending on cartridge and barrel length.

If those numbers are true, and there is a pressure spike associated with the bullet hitting the lands it seems reasonable that the gain twist will help with barrel life

The video made it sound like the material was the real special sause for barrel life.

There is a good bit of conversation about seekins not being the only one doing these things , but it might be unique in that they are doing , material, sin Wave shaped riffling , and gain twist.

I’m excited to see how they shoot i have two seekins and I’m a big fan

I’ve been noticing a drop in Seekins stock levels, and Bud’s seems to have cleared the shelves. EuroOptic is also shipping their rifles with Poly mags instead of CF mags.

My tinfoil hat is telling me that retailers are going to start seeing shipments of new rifles with the new barrel tech by summer, and we’ll be able to try initial quality at least.

My question is if you reload and the bullet supposedly doesnt engage the rifling at the start how do you find jam or find a base to ogive?

This X-ring guy doesn't sound unbiased...

With that said I might be a dreamer, but I really hope new barrel manufacturing approach's and high pressure ammo lives up to the hype and more.

I'm usually pretty skeptical and chalk most claims up to marketing, but I'm fairly impressed by a gun still shooting sub 1moa 10 shot groups after 5000 rounds of 7mm backcountry. I wanna see what other reviewers see in their own testing.

Is there any published data that can substantiate some of these claims about barrel life? (with regards to normal cartridges in that 60-65k psi range.)

I doubt it unless it’s publicly funded and not part of a secret squirrel program.

Worth searching through some literature.

I want to believe…

The physics are solid.

Implementation has been the challenge -- but ECM turns that (mostly) into a software tweak, while simultaneously broadening the range of alloy options. Then add nitriding.

^This. ECM itself is awesome for the precision it can offer, but it's the alloys it opens up for barrels, that just can't realistically be rifled in traditional ways, that is thrilling. We're going to be seeing some really cool stuff in the near future.

I was looking earlier. They don't do prefits for 6cm? wth
