I've got a .338 edge with a short barrel, It's a savage long action with a 17.75" long barrel and a harrels muzzle brake. Didn't want it to be that short, long story, but that's what I could fit in my lathe and still chamber the barrel. IIRC 250 SMK's were going out the end at 2840 FPS. I still haven't shot any heavier bullets from it as of yet. Muzzle blast is tremendous, and I've been thinking of switching to a different brake design, probably the muscle brake, but it might just be splitting hairs. I haven't shot it in a while as I stole the scope for something else and have been undecided on a scope for this one
