Krieger,pacnor and benchmark are my faves. Lately all my builds have been benchmark. I have 2 krieger and 1 pacnor left. In a year and a half I have done 6 benchmark and one more is soon to join the pack lol. Wa company and great quality. If you need a shop that will turn you out a nice rifle let me know and I can send you some info.
Several Broughton currently, and gets my nod every time. But have had a dozen or so Harts over the years, and all have been VERY accurate. Plus, a tour would be a fun bonus👍
I have a Hart on a BR gun. I also have a Shilen. Both are good barrels.Most barrels lose accuracy due to poor cleaning techniques or shooter mishandling. See where I mentioned shooting one out in under 500 rounds.
Hart makes an exceptionally good barrel, they are one of my favorites, but there are many different barrel companies that I believe, also, make exceptional barrels. You can't go wrong with Hart, Krieger, Bartlein, Brux, Lilja, Benchmark, or Broughton.
