I bought a 8lb jug of it last summer. It's doing great in my 7x57 Mauser and shows promise in my 30-06. I have found it's not quite at slow as the H4350 that I have used. And the SW4350 is much much slower.I see some older threads on Shooters World Long Rifle. I have quite a few lbs of this, i bought it over H4350 for my 6XC and a few others that use H4350. Anyone else having good luck with it?
