My POI is the same with the new and old bottle. 300 fps difference can be found when using a brand new bottle of 777, let alone pyrodex.that boat don't float. also never had a bottle clump on me ever.and the 15 yr old bottle i have now, looks as good as the new one... Ray

My BP club tested the powder, and that what we found. It's hard for me to prove that, so I looked for something else to show you.
All I can find at the moment is a test by Toby. This is what he found.
Modern black powder substitutes have come a long ways since Dan Pawlak, of Issiquah, Washington first formulated the earliest form of Pyrodex back in the early to mid 1970s. During the late 1980s, I conducted a "shelf life" test with Pyrodex "RS"...and in the course of 6 months, from October 1 to April 1, I found that a 100 grain charge of the powder, behind a saboted 260-grain Speer .451" JHP lost more than 100 f.p.s. (shot from a 24" barreled Knight MK-85). And by the end of that summer, velocity was down nearly 300 f.p.s. from the velocities I had gotten when I first shot out of that canister of powder a year earlier. And that was a very common complaint with Pyrodex. Once the seal was broken, the powder lost its oomph. Powder used one season could not be used the following season.

You guys have seen my my range session reports. Does GOEX ring a bell?
I've got some T7, Pyrodex, JSG and Blachorn in my powder bag. But I don't think I've shot anything but GOEX in the last year or two.
It's;
1. Consistent.
2. Reliable.
3. All the power needed for the type of hunting I do.
4. Easy cleaning.
5. Inexpensive.
6. Mighty fine smelling.

Now this is not a scientific test. But I had a jug of Pyrodex RS that was over five years old. It was one (unopened) that I had put on a back shelf in a bag with the receipt. So I knew the date I purchased it. When I found it, the price sticker on the lid kind of gave it away too. I am one of these that keep buying stuff on sale. Since then I have learned to rotate my stock.
When I shot that old Pyrodex RS it shot to the same place on the target as a new jug. Whether it lost some fps I can not say as I never owned a chronograph in my life. I used up that old jug just like I would have a new one.
Another powder that I had a long time was Clean Shot. I had purchased what was left of a case of it when a store went out of business. Before I shot off the last jug it had to be over five years old. It went bag every time and seemed accurate at close ranges out of my traditional rifles. Actually it was a fun powder to shoot. I believe that later turned into American Pioneer Powder Company.

I believe the key with ANY powder whether that be Goex, Pyro, 777, BH209, Smokeless, etc. is how you store it. You read any lable of powder and they say a dry cool place. If you make sure the cap is on tight, out of sunlight, dry air, and not in super hot enviro. You will be ok. I just think alot of people are careless with powder.
