[QUOTE="MagnumManiac, post: 1242050, member: 10755"] The theory is this, if each increase in powder is a uniform amount, such as you discovered, then all is well, if a velocity suddenly jumps 200fps, which does happen, then pressure has risen significantly. Also, if everything tracks well, then velocities reduce as powder is increased, then you have gone too far. The brass case, not the primer, will often tell you when max has been reached, stciky extraction, ejector marks and scuffing of the case head are all signs that pressure is excessive, regardless whether the primer looks normal or not.
