![]() Use a break OP, you will not see reduced velocity, or any other vodoo ballistics this guy is touting. A break is different than a ported barrel which you seem to be describing. The powders used in the Beo are magnum pistol powders that achieve 90+ burn efficiency in a 16" barrel. What does burn exerts no more force on the projectile, and is just muzzle flash. Powder is burned in the barrel, and a relatively small portion (if at all if you are a careful reloader) ever burns outside of the barrel. One it leaves the barrel it is external ballistics, and a muzzle brake vents gas, not energy which has no effect after the bullet has left the muzzle. You describe interior ballistics, and say that once the bullet leaves the muzzle there is still internal ballistics that will be affected by a muzzle brake. I found that the heavy MGI rate reducing buffer does help mitigate felt recoil pretty well with the Beowulf which seems to have a noticibly higher bolt/carrier velocity. The Beowulf is a relatively low pressure round that uses very heavy bullets in relation to weight of powder charge and has a very large hole in the end for the majority of the gasses to pass through and also less perpendicular surface area for the gasses to act against. Brakes work best with high pressure cartridges that have lot of powder mass and light bullets as well as small bores (since only the gasses that don't follow the bullet straight through the end of the brake act on the perpendicular surfaces of the brake to reduce recoil). ![]() ![]() A brake slows a portion of the powder (which has obviously changed to a gas but still retains mass). (Recoil is determined by the velocity and mass of both the bullet and gunpowder. They effectively remove a portion of powder charge from the recoil equation. Brakes work by slowing and redirecting gasses at the muzzle.
