A side port with top ports make shooting the big magnums much more enjoyable! My semi-custom 300 rum has a aps brake. Side ports with upper ports and it is a breeze to shoot! Very little recoil and can spot shots at 100 yards with a hot loaded 230gr pill. My sps 300rum has a vias brake and it is affective but dust and spotting of the shots aren't nearly as easy. Now with the upper ports on the brake and nothing on the bottom it forces the barrel down word Flexing the barrel. Could affect accuracy I have been told but my custom will shoot a 3 shot group as a ragged hole at 200 yards. So..
Center Shot Rifles makes the muscle brake. they are a slab or round brake with just side ports no upper ports. No barrel flex with this set up and very affective with spotting shots!

Slab brakes are much more affective as far as my experience goes!

Second question. Would a slab style or side discharge brake be more effective at reduceing muzzle jump than the factory acubrake? I am looking for options to decrease muzzle jump, to make spoting my shots easier, not to mention the dirt that the radial brake blows up. Thanks
