I have both the Nosler number 4 reloading guide and the Lyman 47th reloading handbook.

I am noticing a difference in max loads for different rounds.

One example: .22-250 -Noslerhas 39 grains max load for IMR 4350 @ 3608fps
.22-250 -Lyman has 40 grains max load for IMR 4350 @ 3561fps

As you can see, the max loads differ as does the velocity (no, the velocity is not reversed).

What reloading guide should I go by? What reloading guide doyou use?

Thanks.
