How do you get enough speed out of the 150gr projectiles to beat a 140gr at 500m?
On the ballistics program I have the 140gr Accubond is out performing the a 150 VLD at 500m.

The 140 is starting at 899 m/s and doing 614 m/s at 500m. With 1713 joules of energy, with 10.3 moa drop.

The 150 is starting at 853 m/s and doing 592 m/s at 500m. With 1703 joules of energy, with 11.5 moa drop.


Ok so there is fuck all real world difference there, but if I could get the 150's to go a bit faster they would be the winner. Unfortunately when they do go a bit faster the group blows out over 1.5 moa.
So what speeds are other peolpe getting 150's to go and shoot?
