Looking for quality 30 cal barrel blanks for testing.

I am testing for .308 rifles. Need 1.20" at the breach, 24" min. Straight unfinished, or gradual taper. I need at least .90" at 12" and .80" at 20" from the breach. SS and Chrome-Moly-Vanadium steel is fine. Must have twist of 1:10, 1:11 or 1:11.25. Cut rifling or buttoned rifling. 5R or 4 groove. Prefer very tight bore size (.298 to .300)

I can order at retail, and in some cases at wholesale, so I can buy these blanks. I am looking for something you have that was purchased for a project that never got started. I will pay a fair price, just not retail. Higher prices paid at the top of the list, and less at the bottom. It is also possible that I missed a blank maker that I might consider. These are the quality blanks that I have worked with in the past, and have great results.
