Shooters World SW4350 powder is the slowest of all the 4350 derivatives. As such, it has broad capabilities in moderate calibers where other 4350 derivatives cannot reach 100% loading density.

If you seek accuracy, one of the keys is to find a propellant that can “fill the case and seek maximum velocity”. Several shooters have found this relationship to be true with SW4350, and are impressed with its performance.

But please understand, SW4350 is not exactly the same propellant as H4350. Ranked in fastest to slowest of the 4350 derivatives: H4350, IMR4350, Accurate 4350, SW4350.
