Which powder

First check the length of the bullet against the twist rate of your barrel to ensure it will be stable.
I suggest you plan on 3100fps
There are several online, try this one https://bergerbullets.com/twist-rate-calculator/

You haven't said where you are, some of the above powders aren't available in the UK. I'd look on the Vihtavouri website https://www.vihtavuori.com/reloading-data/rifle-reloading/?cartridge=7

Some brass is better than others (its complicated) but the 'key' is that you need to know the volume and your brass which should all be pretty similar.
If you make up a load for one case and the next is (intenally) smaller then the pressure will be higher.

Do you have a reloading manual ?
If not get one and read it before you start...

N135 around the 25 g mark , 2.26 case overall length . Tikka varmint with 1:7” twist . Very good on foxy no exit at 112 yards . Good accuracy and should be very stable ,1.68 stability factor so well above the 1.5 ideal number  and 3144 fps from 20” barrel . Cheers
