I am very sorry to hear about your expensive investment that didn't work out.
I'd like to share with you what can be done on a budget. Many years ago I used to pay gunsmiths good money, and sometimes wait months, only to find out that the results were "less than satisfactory" to be VERY polite.
That's when I switched to Savage PT actions, which can be had new for $600, and bought a couple of barrel tools from EABCO. I buy reamers and chamber/headspace to my spec's by hand, no lathe. I buy quality barrels that others have given up on from this forum and clean them up.
Attached is a ladder test of my own 6BRO (Optimum) that is a BRDX with Dasher shoulder and taper. The total gun cost (not including scope) was $1,300 (Action $600, stock $500, bbl $200). The Krieger barrel had an unkown round count when I bought it and I've put another 1,000 through it.
Each group is three shots at 50yds. Best group 0.2moa avg (0.1x2). Velocity 3150fps.
