I just ordered a 12LVP in .223 and am looking to rebarrel it to 20 VarTarg. I'm still researching the caliber to see if it's what I want. I'm definitely looking forward to getting this rifle.
I have a 20 Vartarg Improved reamer on order. I'm going to do a slightly longer wildcat with it. Something like 20x40 Imp just for fun.
His post was 3 years ago , I hope he got the Vartarg by now.
