22-250 with 70 and 80 grain berger VLD's ?

Looking for a good starting point for 70's in a 9 twist 22-50

I have Varget, H-380, 760, IMR 3031, 4064, 4320, 4350, to name a few and RE 7,15,19,22,

Also have some 80's laying around that are getting dust on the box. Read that some 9 twists may handle them others may not. Any staring loads to try?

For once I'm not necessarily looking for the fastest load going.

Thanks
