Lol, this is how it goes for those seeking precision performance from their rifles. I did the same thing recently when I bought a Rem700 5R, a Vortex PST and XLR Element chassis. It was a "budget build" I said, no need to spend big money as for its purpose there was such as thing as "accurate enough". I now have the same receiver but it has been trued, has a Krieger barrel installed and is sitting in an XLR Carbon chassis with a Vortex Gen II Razor 3-18x. I'd have saved myself $1000 if I'd have just been honest with myself and done it right the first time, I have no excuse as I've been down this road several times now.
Looks like you'll have one heck of a nice rifle when it's done!
Yikes. I'm just finishing my "budget" precision rifle. 700 AAC-SD in a B&C, Vortex 6-24 FFP. I was kinda counting on that "accurate enough" thing...
