Quickload or experience with H4350 and 6BR

Does anyone know where to start with 105-107 gr bullets?
What sort of velocity should I expect?
Thanks,
Joe

I havent checked it on quick load, but 35.2gns got me 2930 fps with 103gn bullets in 28" barrel. To get that weight in, you need to tap the powder pan slowly into the funnel/drop tube and it is just slightly compressed in my chamber.

Joe,
I ran this through QL. I made some assumptions since you did not specify COAL or barrel length.
32.0 gr. of H4350 with SMK 107's seated to COAL of 2.440 from a 28 in. Bbl will get you 2827 FPS at 50374 psi chamber pressure. This is a compressed load (102.6%). Start 10% lower and work up.

Thanks for running the numbers. I don't have the barrel yet, so I don't know what it will be throated for, or the length.

I have 7 lbs of the stuff so I'll let you guys know how it goes someday when I get the barrel.

Thanks,
Joe
