PXT Rifling - Opinions?

[deewayne2003]

So after coming across this PXT Rifling video, I'm asking myself is this a legit breakthrough or are they simply renaming gain twist rifling?

2,500 rounds of 300 Norma maintaining .6" groups, thats never been done before so yeah I think they are on to something good.

It really only matters for over bore cartridges that normally have short barrel life.

When I was shooting a ton of longrange and PRS I'd burn a 6mm creedmoor barrel out every year(1800rds) then have to start all over again on break in and load developement. So if you can get the advertised 5k rounds that is game changing.
