I went ahead and got the barrel. With a little lathe and mill work, fitted it to a pre-accutrigger Savage 93R17. Just finished bedding it into a Boyd's stock today. May get to shoot it tomorrow. I'll let you know if I do.
I've heard good things about the Green Mountain barrels. I want to put together a .22 Mag with a Lilja barrel. The Savage Magnum rifle is less than 1/2 the cost of an Anschutz donor, so it'll probably be on a Savage action.
