Why can a 338? By their nature these big guns are a heavy unit. It not like your going to have a deer jump up in front of you that you will be able to shoot anyway, will it? (you have to get off the quad first and unhitch the trailer) and unless you have a March even if you do get rifle to shoulder fast enough you wont see it with your 6X bottom end scope. My 33dB ear plugs will always be lighter than your anybrand can. Judging by the look of it, KiwiGregs brakes will out perform any can too. So, as I guess you will have minutes, not second to pull that trigger the brake appears a no brainer to me (with big guns).
I don't have a 338 (or anything real big) so please tell me if I'm wrong. Just logically, from this side of the fence, a can sounds like a waste of time to me.
