You forgot three that should be included in the poll, Brux, Bartlein, and Rock Creek.
When absolute accuracy is on the line, Bartlein, Brux, and Krieger are in the front of my line, and the choice comes down to who has the bore, twist, & contour I want in stock.
I shot Benchrest competition for over 35 years, and set two 1000 yard IBS/World Records with a Krieger, so my favoritism leans that way.
It wouldn't be too far out of line to think most good barrels can out shoot the person pulling the trigger.....
