I had a BR build done last year , custom Turbo action , benchmark barrel .920 " straight, finished at 25 inch , BR stock , Harrells tuner jewell BR trigger . i shoot 50 yrd and 100 yrd , i am very happy with it . it took a bit to learn how the tuner works , thanks to Calvin and others for helping me with good advise on how to tune the rifle , and how to test ammo . i am no expert , i did lots of research on line , check out Killough shooting supply ( Texas ) good info there as to what equipment BR shooters use , some tech articles as well .all the barrels Dennis said are good barrels , i choose Benchmark because it was in stock from Big horn sales in BC . Ammo is the most important thing with .22 rimfire , i learned that real quick , to get the best out of the gun you should lot test ammo , and use the best that you can afford . not sure if you will use a tuner , i know others that dont and have had excellent results as well , mostly Anschutz barrels . my 2 cents .
