"...doesn't cover the 53 grain v-max or the imr 8208 xbr..." The make of the bullet doesn't matter. You load for the bullet weight, not the maker. Hodgdon's site should have imr 8208 xbr data. If they don't list it(don't have time to look myself, now.), pick another powder.
8208 is used at least 10x on that data and for all of the bullet weights I've been considering for now.It looks like it's used for every weight except 45 gr.
Disregard anything sunray says 99.99% of it is just to see himself type.
The mini would be an ok rifle for some fun
