A Friend bought a Double Star/J&T 24” 416 R SS upper a few years ago and was very accurate barrel. He ended up cutting the barrel back to 20”. We suspected the DS/J&T air gauged barrel was a Wilson Arms blank or complete barrel which DS sold. I have a couple of 1:9 twist 6.5 Grendel barrels (16” J&T) and they are good shooters but I haven’t shot any heavier bullets at long range. My Son in Law has shot 129 grain Hornady bullets in his 22” 1:9 twist 6.5 Grendel with good results.
If I were in your situation I’d probably finish ream the barrel you have.
