Suggested Friction Ring/Brake Configuration for 12-Gauge Magnum?

    Greetings,

    I've recently acquired a circa 1977 12-Gauge Magnum A5 (chambered 2.75-3.00"), and to be clear, I've yet to test the gun's ability to properly cycle various shell sizes and loads, but before I get started with it, there seems to be rather mixed views on the recommended friction ring/friction brake configuration to be used with this 3" Magnum model. And so, I'm curious to see what specific configuration other 12-Gauge Mag owners may have found to perform best for them.

    First, some essential background: I expect to use this particular shotgun almost exclusively on geese (not ducks), using primarily 3.0" (1-1/8 to 1-1/4 ounce) steel loads, and for such 3" shells, the Browning literature clearly recommends using the 5-piece (3") friction ring/friction brake configuration shown in the first diagram below. However, a number of professional gunsmiths who are considered experts on the A5 (including the folks at Art's Gun Shop in Missouri), discourage the use of this 5-piece (3") arrangement in favor of the alternate 2-piece (2-3/4") arrangement shown in the second diagram below.

    Basically, the consensus seems to be as follows: "Use the LEAST number of friction ring/friction brake components possible", that still allow the gun to cycle properly, and of course, with a heavy 3" load, that would almost always prove to be the 2-piece (2-3/4" arrangement), which is in stark contrast to the official Browning literature, including the Owners Manual and the Field Service Manual.

    Can anyone shed further light on the subject for me? I'd sure appreciate it!

    Thank you!

    I don’t have a Magnum, but the principle is the same for all: Use the most friction that the gun will operate with. If you use less, the gun will operate great while beating itself, and you, to pieces.

    Maybe whoever you talked to at Art’s thought you were asking the usual question— how to fire low powered loads in a Magnum.

    If you are going to shoot 3” shells, set it up for them. If it doesn’t cycle, add some oil to the magazine before removing friction pieces.

    Rudy . . . Thank you for your reply and the information it provided. The gun has been fully dissembled and thoroughly cleaned, and per numerous recommendations including your own, I do in-fact plan on applying a light coat of SAE 0-20 synthetic oil to the inside of the friction brake(s) and exterior of the magazine tube. And, that being the case, it sounds like you're firmly recommending the 5-piece (3") configuration, even when adequately lubed, unless and until it fails to cycle properly. So, I guess I'll start there and see how it actually performs once I'm at the shooting range. Thanks again.
