If I could only have 1 powder for all my reloading it would be 2400 !!
Do I have other powders YES.
Another powder that`ll perform superb but can be hard to measure is
No exp with 300MP
BUT 2400 was the factory powder for yrs. in the 357 Magnum.
H-110 performs well , but just to blasty & flashy for my hunting loads .
