VIHTAVUORI CONVERSION 32 H AND R

[WindyCity Red]

I'm changing bullet weights on 32 H and R from 100 gr rnfp to 78  grain rn using VV310.  I WAS using 2.0 gr with the 100, but can't find a formula for the 78 grain with VV310.  I checked the VV web site to no avail.....ANY HELP/SUGGESTIONS would be appreciated.

Page 6 shows 2.0 gr for a 76gr bullet. Sorry, I couldn't figure out how to copy and paste the page.

Please read that data closely. The 1 grain load is referenced in a .32 S&W. The results in a .32 H&R might not be what you expect.

According to the VV load data book I've got for 32 H&R

N310 76 gr. FP dia. .313,

2.0 gr. at 676 fps

2.4 gr. at 782 fps

 

Starline Brass

WSP magnum Primer

Roll crimp

Gun used for the above was a Ruger Single six with a 6" barrel.

 

Hope that helps.
