Anyone shoot Piledrivers .22 in Fx STX barrel?

Has anyone tried to shoot H&N Piledrivers with the new smoothTwist "X" barrel in .22 cal.
Does it do well? Is it accurate?
I'm getting my Impact "X" tomorrow and I wanted to know if these slugs would do well in the new barrel?

Hopefully someone out there has tried these.

Thank you in advance!
