[QUOTE="Kennibear, post: 981370, member: 51650"] I chronograph everything because in my experience the velocity increase flattens out (quits increasing velocity) at max pressure. The velocity increase is linear with increasing powder weight until you approach max where it drops pretty fast. That is why so many old time reloaders have no problem cutting back on powder charges as the velocity loss is minimal. I like slightly compressed charges as the powder position in the case is not a factor then. But Lefty is correct as to heavily compressed charges altering the load length. My difficulty with extreme compression is the bullet punch dings up the bullet nose from the excess bullet seating pressure. KB [/QUOTE]
