New proof PXT Gain twist barrels

[Coleredding00]

Sounds like interesting tech. Bartlein has been doing gain twist for a long time, but more to the likes of 1:14-1:5, Proof is claiming 1:500 start twist ending in 8 twist.

If the claims of barrel life increase, could be good for the 6UM when the 6mm variants launch. A test 300 Norma barrel went over 2700 rounds still shooting.

They claim 20-30% reduction in dispersion too.

Looks like it’s only in their carbon wrapped barrels for now. Hopefully they start updating the steel blanks soon

No 6mm either. Which is weird. I’m sure they’ll roll out more options over time

Agree. I’d love to get a Creedmoor or GT barrel with basically unlimited barrel life.

My big question is going to be how short of a barrel can they make, and still get the gain twist benefits?

There is another video of a 14.5 AR barrel, and there is 16.5 22 cal blanks on their website.

Pretty interesting. Would love to get another 50% lifespan out of a precision barrel.

They’ve got a 7 BC barrel with a claimed 5000 rounds on it that’s still shooting .7 moa 10 round groups

I'm curious to see what would happen with this and a structured barrel. They have claims for longer barrel life on both. It may have some really sweet benefits.

Is interesting. Also interesting to see what Frank Green had to say. That guy knows a thing or two about barrels

New PROOF Research PXT barrels

Nice to see some refinements. Appears this is similar to what Seekins is doing with the SIC barrels...?

This is super interesting

The Hornady podcast on it today was pretty interesting as well.

I hope they come out with the pxt in the steel barrels soon. I got a 25 creed coming together slowly and id like to try the new barrel tech out.

The Hide has a barrel expert’s take on it for another perspective. That said I hope the claims are true.

Does anyone know if it’s feasible or if they are working on making standard cartridges with these casings? With the 7BC the steel casing is supposed to handle the increased pressure but then I remember folks talking about actions needing to be beefed up too so wasn’t sure if both are true or if it’s a real possibility to see a .308 or other standard short action cartridges at 80k. .223 would be awesome too. Proof saying the industry is moving to 80k so I’m really hoping they are working on standard cartridges.
