I have some .257 90 grain blitzking. I want to load for a coyote round. I have latest sierra manual and they list no data for these bullets. They list for the 90 grain hpbt. I have checked and they don't say that the data is interchangeable so I am at a loss why they would completely omit data for one of their own bullets in their own manual.

I'd venture to say that they do not test every bullet powder combination they sell. I am sure they test a few combinations and extrapolate the rest of the data. You will be fine using the BK just do not start testing at max. Like any other reloading, start low and work up. What powder are you wanting to use?

I have i4350 and i4831 and both have loads listed in the sierra manual so that's where I'm gonna start if I don't like them I have some varget for my 308 loads so I may try it too |

Those will work for you. You should be able to get around 3400 fps unless you have a short barrel. I have read some good things about RL25 with the 90 BK in a 25-06, but I have not tried it personally.
