6mm ppc need a load for Reloder 12 powder

I need a load for my 6mm ppc using Reloder 12. This the last lb I have and want to use it up. It was manufactured in 1991. Still in excellent shape
Using 70 g Sierra Match King bullets , 63 g Rubright Bullets and 60 g Sierra Varminter bullets. Also using 205M Primers. These are going to be used for targeting. I have just about exhausted my resources in finding a good load for these components. Thought I would ask the pros.
I would also like to try this powder in my 250/3000 Sav using 87g Burger bullets. Any ideas on a load ? 455

You are gonna struggle to find load data for a discontinued powder that old.

My suspicion is that RL 12 is too slow for the small cased 6MM PPC. My opinion only and it could be false as I have never used RL 12. It has a similar burn rate as TAC, IMR 4064, VV N530 for what it is worth. Burn rates are not to be used to interpolate data.

I have a bit of data for RL 7, but nothing for RL 12.

The only data I could find in relation to the 250 was a 75 gr bullet. Nothing more.
