For now or until you have time to develope a load - use the powerbelts - 295 & up is a good suggestion....
Theway the powerbelt works is the force of the explosion of the powder on the bottom of the bullet forces the bullet base to expand up against your barrel and into contact with the riflelings holding in the pressure... I would suggest 90 to 100 grains of T7-2f.
You will be able to get those Barnes bullets to work but you will have to change sabots to a MMP HPH-24 or a Harvester...
