Re: newbie ? 7.5 swiss
here's a pic of the finished products. the COL of the GP11 is 3.043. my batch of Sierra 180gr has avg COL of 3.023. my batch of Hornady 150gr avg COL is 3.013. both are BTSpitzers. COLs in my original post are what the book shows, 2.900 & 2.790, respectively. my question is, do I press the bullets all the way down to the book specs for COL or leave them at the length of a round I'm sure works in my rifle, or even longer after I measure where my lands & grooves begin. if I leave them where they are is that going to decrease the pressure since there would be more volume in the case. I'm not looking for a HOT load in this 100+ y.o. rifle, just something consistent. BTW, the LEE pkg insert for the dies shows a Max. Overall Length of 3.051. thanks for your help.
