BH209 Discovery

[Brathany]

I got my smoke pole out yesterday (T/C Encore FX Pro Hunter) and chrono'd some 205gr Barnes T-EZ. I let the gun and components cool to match ambient temp of 45F. I got 1988fps average. 84gr by weight BH209. I thought that a little slow, so I tested the BH209 volume tubes and my brass volume charger. 120gr by volume of BH209 came in at 96gr by weight every time I tested it on the Chargemaster 1500. So, I don't think the 70% rule of Volume to grain weight applies to BH209. Possibly because it's extruded?

It's been known since it first became available that each different lot# had a different volume to weight ratio.
Lot#41 might be what you're using???? The 120gr volume measure of lot#41 averages 96grs weight.

Bottle says 02261418. Got in 2015-2016. Western Powder Company made. Guess Hodgdon bought them in 2020.

Though I bought a 5lb jug of it and split with a friend. This single bottle might not be that lot number of the 5lbs bottle. Either way, I know I mixed it all up between this single and that 2.5lbs of that 5lbs bottle. As I do all new batches of the same powder.

That's been around for awhile
