[QUOTE=Sako85; they grouped so well I didnt try more powder.

Cheers for the Info[/QUOTE]

When I worked up my load I started low and worked up to well above the 2900 fps but started getting some pressure signs.
The most interesting thing was that there was 350 fps between the starting load and the over pressure load and every shot went into a single 25mm group despite the velocity spread
It was so accurate and consistent that once I found the pressure and dropped back 0.5 grains I started doing accuracy testing and at 2900 fps it shoots 8mm groups.
End of testing
Load 50 rounds and go and shoot a heap of deer.

Then I changed to Bertram brass and thought I should test it all again.
But the same load and seating dept shot to the exact same poa and 8mm groups.
