I also have a BAR, made in 1971, and a Ruger 77, both in .338. The Browning handles recoil better, especially as it was magna-ported, and is more acurate. However, the BAR jammed once on me in a hunt and I have never trusted is since. While I had cleaned out the barrel and action after several range trips, I had not broken it down and fouling had gotten into the action rod area, IIRC. Cleaned it out and it works perfectly.
So, if you remember to detail strip the rifle after shooting it, there should be no problems. They are neat rifles...Bruce in Utah
