[QUOTE="poon, post: 69552, member: 4270"] Hi shooters. I was just wondering why the Vithavuori guide states two different loading data for 55 grain bullets a FMJBT and a FMJ ?.The max load of these two differs 1.6 grain! What data should I use for a Sierra Gameking/Blitzking boattail? I have primer starting cratering with this load: Brass: Lapua ,load;24.5 N133.primer Fed.BR Bullet :55 grain Sierra Blitzking. Could this be because of pressure? Or a weak spring? Poon [/QUOTE]
