JE Custom? I was looking at your website.. Very interesting reading. Can you explain how you "tune" a brake to a specific round? Is it based on gas flow? Bullet diameter and velocity? Do you actually "flow" the brake and have to machine it a certain way? Thanks,
Mike
Tuning a brake requires many factors of your load, cartridge, case volume, bullet weight, velocity, type of powder, (Single base or double base) powder charge, and barrel length. Armed with this information,we know how much gas volume is generated and the pressure at the brake.
Using our formula( Which is a secret for patent purposes) we can determine the size of the ports and the number for machining. the brakes are literally one of a kind because of this machined difference.
The formula was developed using a recoil device that precisely measured recoil of each change we made to the brake to determine the best performance.
During testing, we found that a properly Tuned brake could produce
from 8% to as much as 20% more recoil reduction than a standard mass produced brake, depending on the cartridge and rifle combination.
The point to all of this testing was to prove that a muzzle brake is more than a piece of steel with some holes or ports cut in it and a hole through it slightly larger than the bullet. Considering the dynamics of what a muzzle brake has to deal with, and the many different cartridges and loads, they can be very complicated in there design if it is to reach the highest performance levels.
For every single cartridge and load there are differences needed to get the most from the brake. With mass produced brakes , tuning is impossible for this reason. Based on there design, some brakes perform better on one rifle and cartridge than another because if the difference between then. (A certain brake may produce more or less recoil reduction in 7mm mag, than in 300 win mag because of these differences).
