[QUOTE="bigngreen, post: 483009, member: 13632"] Not monitoring your case length is some bad ju ju man!! Major pressure spikes going on when the brass jams into the throat with a bullet still in the neck of the case. I measure every case every time I reload after learning some of the undesirable effects of waaayyyy over pressure!!! I figured this out when I had a few shots going like 6 MOA higher at 1200yrds, couldn't figure it out till I was getting ready to reload and I found I was .012 long on a few cases. Do the math 270 WSM @ 3341 fps gaining 6 MOA, it scared the crap out of me so I started paying attention to what I was doing!!! [/QUOTE]
