Using obsolete Win 680 powder.

Years ago and I mean years ago I bought 10 lbs. of Win 680 powder from a local gun shop because it was no longer being made. Got a great price for it, like $8.00 a can. Was using it for my .30 Herrett. Worked really well. The other day as I was sitting in my reloading room I started looking at some of my old reloading manuals that listed Win 680. It was only 2 behind Accurate 1680 in burn rate, so I thought being as powder is so hard to get why not try this in my 300 blk out. It worked great. 15.4 grs. and it shot some very tight groups with a Hornady 150.0 yr. SP. Cycled great too, no pressure signs. Why not. Now I can load some rounds up and shoot plus get rid of some old powder. I don't shoot the .30 Herrett much anymore.
