[QUOTE="J E Custom, post: 1486425, member: 2736"] My recommendation would be to test with the brake because of the number of shots fired and the reduction in recoil making for a more pleasant experience during the process and a more apprehensive load testing . Load velocity will not change with the brake or without it and the attention to position and trigger control improves without the added recoil. After the test with the brake you will be able to tell if or what the change is without the brake and decide which way to go much easier. If a muzzle brake is installed correctly, It has no effect on the bullet. Due to harmonics and weight it may, effect the POI and the accuracy but My experiences have been for the better. The low pressure of the air in the barrel ahead of the bullet has no effect on the accuracy or velocity or the performance of the brake because when compressed by the bullet it increases only by the volume of the bore. Depending on the type of powder (Single base or double base) the powder will increase in volume by 1500 to 1700 times the powder volume charge and reach very high pressures (Normal SAMMI pressures are anywhere from 46,000 Psi to 65,000 Psi). This gas is released after the bullet is gone from the bore at a lower pressure (Normally 12,000 to 18,000 Psi) Maximum pressure in a barrel occurs between 1/2 and 2/3 the length depending on the powder and projectile weight and pressure starts dropping until it exits. If the barrel is to short to burn all of the powder efficiently and the gas is allowed to exit at maximum pressure, sound levels and muzzle flash will be terrible and for the most part unacceptable. This is the reason that brakes normally don't have any negative effect on the bullet . J E CUSTOM [/QUOTE]
