The 10t was $500 on sale from $600. It's ready to shoot right out of the box. Don't forget it comes with a nice oversized bolt handle and scope base that I'd value at about $80 (ballpark). You are talking about a proven quality sub moa rifle with a few extras for $500! Did I mention it has dbm too?

Even if you still want to build and tinker this would be a solid platform to start. And you can be shooting while you save for the real nice stuff. Take the extra $250 ($750 you said you'd spend) and put it toward a reloading kit. You will save a ton of money reloading. No manufacturer can reload bullets as you can for your particular rifle. You will shoot better regardless of what rifle you decide on.
