I`m getting all lined up to add the 22BR version to my arsenal. I picked up a Krieger #4 with 7.7" twist a few months back. I will try the 75 grain A-Max`s first and work down in weight to see if the accuracy holds up. I been promoting the 6BR when I first had mine done, I hope some of that helped push some over the edge....... I have 2 6BR barrels a 12" twist and a 8.5" twist. They are darlings, but to heavy for anything but a bench, this #4 will be a great crow duster.
You should be happy with the 22BR. Bob Milek was hot on them a number of years ago, so I had one built. It is a shooter, 3 shots into 3/8" at 100 yards. It's a sporter, not a bench rifle.
