.400 = 4 tenths of an inch not 4 thousands. .004 would be 4 thousands. I can understand why folks might be just a little skeptical of someone saying they are shooting 4 thousands of an inch groups. Wow, you could take your BAR ant take the benchrest world by storm....LOL
Now, 4 tenths (0.4"CTC) is believable. One of the work up groups I shot with the Game Kings was 0.511"CTC. You're quite lucky to be getting 0.4"CTC with of off the shelf Remington 165 grain Core-Lokts. It just goes to show you that every gun is different, and some can be very particular about what you shoot in them. Obviously, your gun likes the Remington 165 grain Core-Lokts.
Others may question the accuracy of a BAR because most everyone says that a bolt action is more accurate than a semi-auto. That is a true statement! Otherwise, bolt actions would not dominate the bench rest competitions. However, for hunting purposes, most folks consider 1 MOA the standard by which hunting guns are judged, and BAR's are quite capable of MOA and even sub MOA accuracy if you find the right load for each gun.
As I mentioned in a previous post, I think that with a little "fine tuning" of my Game King load, I will be able to consistently shoot 1/2" groups @ 100 Yds with my BAR.
