Miller-
If I had access to that measure I could gauge it myself (down to .0001" in whatever direction), but it's only a photograph and this is the closest I've been to it.
I don't know where it is - just picked it off the web some time in the past.
Very much interested in seeing what a 'regulated' fixed powder measure from a vintage Brit (cased tool kit for instance) rifle will do (by way of grains weight) with Goex FFg.
The adjustable measure I'd used (one of many such mid-century USA made adjustable measures in my stash) is a mid-19th century American 1ounce/2-1/2Drm - 2ounce/5Drm adjustable model from Torrington.
As things tend to be a bit different from shore to shore, and things out here don't always agree with things in the UK, I'm interested to see how today's Goex FFg powder regulates by weight through a vintage Brit fixed measure.
For instance, if that 130 Grain fixed measure was available to me, I'd throw a regulated charge of Goex FFg through it and give it a go on my Grains scale in a hot minute.
Cheers
Tinker
