If this has already been discussed my apologies, anyway here's the scoop. I've got a .338 edge shooting the standard 300 gn SMK load. It's about a 13# rifle with a 30" sendero countour barrel. It's currently wearing a 3 port muzzle brake. It's a very accurate rifle but my problem is I'm experiencing some muzzle jump that's affecting my accuracy at extended ranges. Is there any one muzzle brake that is absolutely the most effective recoil reducer? I was looking at the 5 port painkiller brake from APS. Any input will be greatly appreciated.
