Having one built off a Stiller precision action w. a Hart barrel. Anyone else build one?

i built one a few years back stiller ss single shot viper action 20moa rail, nightforce 8x32x50 30mm tube npr2 reticle. I have two barrel a 6.5x284 shelin and a 243AI.douglas. just got this barrel and have not shot it any.
I think they all make high quality barrels hart and kreiger are two that I would get but there lead times are very long.
You will like the stiller action, very well made
