I have no idea what you are talking about. It's pretty obvious why the brake with the bigger hole is much less efficient. ![]() 22" circle that the escaping gasses can pass straight through and thereby have no effect on recoil reduction is. The efficiency of a brake is determined, in part, by the size of the bore. If the weight of the propellant is a relatively small portion of the mass you are accelerating, then your brake is less effective. A brake works by negating some of the mass of the propellant in the equation by slowing/redirecting it at the muzzle. This includes the weight of powder as well as the bullet. Recoil is generated by accelerating mass down the barrel. With this combination you might be able to get close to a 50% reduction in recoil. Shooting a 35 grain bullet over 40 grains of powder means you have a lot of mass in the gasses (in relation to bullet mass) to act against a much more efficient brake(due to the much smaller hole through it). At best you would be lucky to reduce recoil by 5-10% with any reasonable sized brake on a Beowulf.Ī brake used on a rifle chambered in something like 22-250 on the other hand is very effective. Even a tank brake which is very effecient, gets less efficient as the size of the bore gets larger in relation to the overall diameter and length meaning that even a tank brake is pretty inefficient with a greater than 1/2" hole through it. The fact is that with 50 grains of powder and a 400 grain bullet, even if you could build a brake that's 100% effecient (and it would have to be the size of a Folger's can to even get close) you could only reduce recoil by 20%. Did I say anything about reduced velocity? Or anything at all about ballistics for that matter? Type of powder, or weather it's burning inside or outside of the barrel, burn efficiency, etc? I don't think you understand how a brake works. pepperpot like I said earlier does nothing but protect the threads IMO. Get the tank brake, or the KA brake if you want to do anything to reduce recoil. If you intend to reload for the Beo I recommend you purchase Quickloads. 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.
