Re: Disappointing 308 MV.......and......which powder in Lapua factory 308?
Thanks, I've spent all afternoon mulling this over in the back of my mind, waiting for the flash of inspiration.
Just spent 1hr fudging every variable (given a fixed 2722fps mv rather than the fudged 2580 I've been using) tried messing with pressure, alt, scope height, retard value, BC etc [img]/ubbthreads/images/graemlins/crazy.gif[/img] in order to try to match field observations. No success, only 2580 mv puts me in the parish [img]/ubbthreads/images/graemlins/mad.gif[/img]
Until, literally 10min ago, it occurred to me that the S&B might not be giving me spot on 10mm clicks. What if they were, say, 9mm clicks?
I just input a formula that divides my 1cm click values by 0.9, and lo and behold, at an mv of 2722 I am firmly in the parish! 0.88 seems closer yet.
This will need a bit more investigation, but I think this may be EUREKA
PS I'll drop you an email regarding the ACI
