[QUOTE="Jimm, post: 75941, member: 9"] Thanks guys for your posts. The rifle in question is custom barreled/chambered for a std. .300 win mag. Loads mentioned were within even the reload manuals guidelines. Base line for me seems to be to check the dimensions of the new unfired brass . Then ,check the fired brass against that .This I have done ,and the ladder test with velocities recorded for each shot and case head expansion as well are matchingt the data of the manual I'm using(Sierra). I guess the reason I asked this quesation in the first place is that the classic pressure signs did not appear(i.e. heavy bolt lift, cratered primers,excessive shiny spots on the face of the head. Case head expansion is the only indication of max pressure that I was able to observe. Please , all that are so inclined , let us hear from you on this. Jim [/QUOTE]
