[QUOTE="Limbic, post: 331722, member: 11905"] I've shot 400-500 of the 168's and 180's combined from a 7mm RemMag with a 26" shilen barrel. 1:9 twist. I shoot in warm weather at 250 feet above sea level. Roughly. I found that the accuracy for the 168's was best at about 3000 fps. I was using 64g of RL22 I believe. .080 off the lands! Routine 1/2MOA. I could push it faster but accuracy dropped off. Because of this I switched to 180's. .01 off the lands. Near max load of Retumbo (68g) gives me 2950 fps with the same 1/2MOA accuracy out to 300 yards (shooting range max). I've run the numbers through my ballistic calculator and at 300 yards this load hits about like a factory 300 win mag with 200g accubonds. More than one person has commented that 3000 fps is the magic # for the 7mm VLD. BTW where do you get 7mm Laupa brass? [/QUOTE]
