    What would difference be for say 338 RUM or edge in a 27" barrel with brake vs 30" with brake? Shooting 300 grain pills of coarse.

    It is really hard to say as not all barrels are equal but I would not expect even 40fps in a truly equal barrel. I shoot a very mild 89.0 grain load of h1000 with 300grn in my edge with a 24" savage factory barrel and it nets a verified 2781fps. I can run 2850fps if I load it up to 92 grains. Between those longer lengths in that bore size, The difference will be very little.
