Best powder for 140's in 6.5x55?

[1shot]

I've been shooting an improved version of the Swede called the GWI for several years and found a load of H-4831sc that just absolutely hammers at 1,000 yds. Velocity is 3,070fps. using 140 JLK bullets.
I hope this helps,
Lloyd

IMR 4350 & H4350 both work well for me.
