[QUOTE="J E Custom, post: 1298000, member: 2736"] There are two kinds of recoil when firing a cartridge here is an expiation that may help. [url=http://www.jecustom.com/index.php?pg=Home&cmd=Cell&cell=FAQ]www.jecustom.com - FAQ's[/url] So If the bullet weight is the same and velocity is the same, the only thing that changes is the amount of powder and this will effect the "Gas Recoil". If less powder is used the end results will be less recoil. A more efficient case design will normally need less powder to produce the same velocity. the reason is that the power curve will be different and have more time at peak pressure Due to flame front differences. (The shorter fatter case produces higher pressures sooner and therefore can match velocities with less powder) Less powder produces less gas recoil because of less volume of gas. Muzzle brakes can only effect the gas recoil and interestingly enough the higher the powder weight, the higher the recoil but the more efficient the brake is. So even though the 300 WSM can match the 300 WM in velocity, it will produce less recoil because of less powder. J E CUSTOM [/QUOTE]
