Federal 150 vs CCI 300 primers?

[MovedWest]

I have a recipe from older Alliant book for 44 magnum that is built on Federal 150 primers. Do any of you know if there would be any difference in loads by substituting CCI 300's?

For reference the load is:
300gr XTP
15.9gr 2400
Fed 150 primer
1.600" OAL
-> 1190fps @ 35kpsi

That looks like a healthy load. I'd start with 10% below that load to start and watch closely for over pressure signs.

Just tried some new loads with this recipe above with the CCI300's at the range last night. They're pretty evenly matched.
