Because I'm already running over book max with that charge and when I increased the charge I started to get scraping (smile) on the case head.
Trying to get to the next accuracy node started to cause a slightly sticky bolt
Even using H1000 I found I difficult to break the 2900 fps mark with the amax and the 168 Sierras
64grs h4831 gives me 2743fps and is super accurate from my 7wsm. I have had better luck with velocity using 4350 from my 7wsm and the 162s. I found an accurate load @ 2900fps with it and I could not get there with 4831.
