Midas, this is the data I got from Geoff at Woodleigh 1/31/08.
We haven't tried 4350 with the 450gr bullets.
The loads we recommend as follows:-
Federal 215 primer
450gr SN bullet
94 grains IMR 4831 for 2304 fps
94 grains H 4831SC for 2300 fps
100-105 grains H1000 for 2100-2200 fps.
For FMJ reduce by 3 to 5 grains then work up if necessary.
Regards,
Geoff McDonald.
