[QUOTE="Michael Eichele, post: 431187, member: 1007"] Ok, in some circumstances you are right. Heavier cases dont always meen less volume. You are 100% correct. So lets assume that when I was refering to heavier cases I was refering to the ones that are thicker. That said, I have experience the opposite as you. Using top loads in my 338 Edge using one case brand and lot and using the same powder charge with 'thicker' walled cases from a different lot#, I have has sticky bolts and cratered primers along with higher velocities. Going back to the original cases manifested average velocities and no sticky bolt. Granted I dont have a pressure trace but it seems clear to me that there can be differences. Espescially since it happens to other shooters and me with other guns in similar circumstances. Of course like alot of other things, it is relative. If you are not using max loads and the difference can be much less. The closer you get to maximum pressures, the more sensitive things can be problems become compounded due to the 'little things'. Call it what you want but there are circumstances where thicker cases can and do cause higher pressures. [/QUOTE]
