I have been using Belgium made BARs since about 1970-71. I have had every caliber printed in Belgium. The only one I ever had that would not shoot some factory load under 1 1/2" was a Gd I 7mm mag. The best for accuracy was a .270 that was an honest 1/2" shooter with 130 CoreLokt.
I never had one that did not feed and fire. I basically sold all them when I started hand loading. They sometimes dented brass and all semis scatter brass about in the grass and weeds. Then I bought a pair of .30-06 and had one bored out to .338-06. That one had a tight chamber and it needed the full bolt drop to make sure the rounds were chambered when charging the barrel from the magazine. A slight push on the operating handle solved that. No problem when fired and picking up a round to reload.
I still have an '06 made in 1970 in a beautiful hand engraved GdIII wearing about grade IV or V wood.
The all steed guns are a little heavy, and the magnums are heavy. At 79 YO, I don't walk far anymore, but rather hunt from some form of ambush, be it a box blind, ground blind, a brush hide, or just park my Mule and watch a trail, food plot or water. They make some alloy framed guns that get under 7 #. Since the bolt locks into the barrel, this is no sacrifice in strength. No problem.
The only parts that I ever replaced on a BAR were a couple of recoil buffers which appear to be made of nylon. Cousin's kid failed to clean his for a few years and I decided that a new gas piston was in order from pitting. It did still work. The triggers can be smoothed by using thin strips of 800-1000 grit paper between the trigger and sear.
I got my first one as the result of total dissatisfaction with a 742. I like the quick repeat shot capability. I once went five for five with the .338.06 before the rest of a herd of South Texas pigs could flee my food plot. Next day the coyote hunting got good.
I have not used but see good comments on another forum about the Benelli.
BTW, the only interest that I have in Browning is my BAR, my Pigeon Grade 20 ga Superposed, a pair of wasp waist .22s, and my A-5. Add: I for got the three Safari bolt guns. They have made some good stuff.
Best wishes,
