Accelerator load data help?
 

I'm loading my .308 with 70 gr bergers I had left over. They are boat tails and I hope they work in the sabot.
Any load data would be helpful.
I have the info from E. Arther Brown.
Does not include data for 70 gr.
Do you use the flare tool? Or need to? Is it advisable to use some amount of crimp since the bullet is a BT?
I'm trying 44.5gr IMR 4198.
