I've got an old Lee Loader for 6.5x55 but I have none of the powders listed on the chart that came with it. I do have H4350 and H4831SC though.

It came with Lee scoop #167

I was wondering if anyone knows how I can find out what a full scoop of H4350 weighs in #167.

What about H4831SC?

You`ll have to weight the dipper to find out what charge weight you`re getting. Lee quit offering those dippers years ago and went to dippers marked by volume in CC instead of just a random number set. The old dipper set I have doesn`t list H4350 as a powder option but does include IMR4350. I don`t believe the hodgdon version was available at the time your dipper was made.

I found that thanks, but I have an old Lee kit and it doesn't say which of the scoops on the chart you provided corresponds to the old #167 dipper.

I recommemd you buy a powder scale.

It does not have to be an expensive one, just a basic scale.

You and I might have a different technique and our charges from the same lee dipper might be different.

When I was in college I used lee dippers to load 44 Mag and 264 Winchester mag with perfect results. However my charges were not MAX, so a grain or so difference would not make a dangerous difference.
The 264 loads shot under and inch using the dipper.
I loaded the 44's on a Lyman tong tool and the 264's with a Lee loader.
