[QUOTE="timeless61, post: 443644, member: 13530"] no, my loads are different, I did basically what I did for the SMK, my load development was not too crazy for it, find my max and back off some, and it always yielded single digit ES with the smk and older powder, at every velocity because I shot the same string of charges on different days, and still each velocity was within single digits of each other. now, the bergers, I did not shoot each load through a chronograph when finding my max, I did not have a working chronograph at the time I measured the cases, and I am now reloading for useful case life, which is 94 grains max with the berger and 93 grains max with the smk. so i backed off some, but am just baffled by the ES comparing it to load development for the smk. with the smk as I said even on different days every powder charge was very close to the same charge's velocity on a different day. also, my pressure signs on a load that I know is nowhere near the top max, let alone not even max where I had case expansion. on this rifle and others, my cases expand before I even show any pressure signs, and there was a direct correlation between the case expansion and primer pockets loosening too much so that is why I am loading like I am currently. maybe I just got extremely lucky with the SMK, I am not sure, I just read a bit about the bergers on here, and most people were getting the same performance with the berger as the SMK, with different charges still, but the H1000 and cci 250 combo was working well.
