90 CX for reloading

[Bassfish1952]

Ok I have some Hornady .243 6mm 90gr CX bullets , it looks like LEVERevolution powder can be had and Hornady on their reloading page said they used Federal 205 primers which can be gotten 

I have 8 boxes of Hornady 103gr ELD-X ammo and will have a cz527 with a 24" barrel when PacNor sends it back 

So should I be able to match what is printed in their app. it lists 3000 fps for 31.7 gr and 3050 fps for 32.3 gr and how far down from max load is it safe to start at ?

Also Hornady listed Federal primers but are they the ones to use 

Turns out I know someone that reloads I just have to get the 6mm ARC stuff

Thanks
