Hi PAULT , I hope this will assist as we normaly use Vit 150 as our go to powder for accuracy loads in the 30.06.
1. Lapua case/ hornady 150grn SP / 53.5 grains N150 / CCI 200 LR
2. Lapua case / Hornady 165 grn GMX / 53 grains N150 / CCI 200 LR
3. Lapua case /hornady 165 grn interbond /52.5 grn N150 / CCI 200 LR
all three loads were giving excellent accuracy in the rifles for which they were developed and the terminal performance on game animals terminal .as with any load start 10% below and work up gradually
yours respectfully Mike Norris Brock and Norris Custom Rifles
as a foot note would highly recommend the GMX or interbond on boar rather than the SST. You may find it too fragile to penetrate fully the gristle shoulder plate on a big boar. The GMX Bullets in particular are fantastic . Being a monolithic guilding metal bullet they will not break up or shed their jackets yet they will expand on small deer and antelope with very little carcass damge.
