Both are a waste of time and will kill the resale of your rifle. If you want more terminal performance, go to a 9.3x62, it has a real advantage.
Don't trust anything you read on improved cartridges unless the pressure and velocity dated is contemporary.
Ackley and most other wildcatters "put their thumb on the scale" when it came to pressure and velocity.
If you have a 35 W leave it alone. It will kill anything in the lower 48 right now.
