I have 3 reload kits that are about 25 years old. I had a bunch of Estes BP motors too and those launched just fine. What are the odds the reloads are still good? I have an H97 and a G75.
nice snarky comment. I'm not certain why you'd give advice about something you're not certain of and apparently have no experience in. He had a concern and was looking for actionable advice, and if you don't have any, well....maybe not comment? Bad advice is worse then no advice. I'm glad the OP went looking for advice about something he wasn't certain of@cbrarick I bow to your knowledge of grain configuration. Why is grain more correct than slug ?
I've read a lot about the delays being affected and becoming longer. I have no direct experience but I did ground test an old D reload a couple of years ago. It burned just fine, the delay seemed pretty long but I didn't time it so I can't say if it was the correct delay or not.I have 3 reload kits that are about 25 years old.

How is that possible? I'm not super familiar with the history of the company, but I thought that AMW was known as Kosdon East up until the late 90s. And Kosdon came out with his reloadable motors in the very early 90s.I recently burnt a AMW green with a 1977 manufacture date. that's not a typo, really 1977. And I was at least the third owner of them.

As far as grains vs slugs, well, why don't you look up the assembly instructions for either motor and see what Aerotech calls them. Here's a link to make it easy: https://www.rocketmotorparts.com/page/instructions
if you prefer CTI here's their link http://www.pro38.com/instructions.php
or Loki if that's better https://lokiresearch.com/page/Documents
if you have access to the EX sub-forum you will find that we call them grains as well.
so that covers all currently certified manufactures as well as the EX world........
when I look up the word slug, the fourth definition of Oxford's dictionary is the closest at "an elongated, typically rounded piece of metal." Well, it's not that.
I think that as long as there is no observable swelling of the propellant [grains] and the [cores] are clear they’re good odds. I would lightly sand the [cores] and any visible oxidation on the grain surface and load’um up.
Lol. Nomenclature foul!nice snarky comment. I'm not certain why you'd give advice about something you're not certain of and apparently have no experience in.

uggh can't find a picture i took of the package, it's posted either here or FB clearly gives a 1977 date code (unless they fibbed but i flew it in honor of Gloria and Robert wasn't surprised by the date code)
CORRECT!!!How is that possible? I'm not super familiar with the history of the company, but I thought that AMW was known as Kosdon East up until the late 90s. And Kosdon came out with his reloadable motors in the very early 90s.
Probably a '97 date code that wasn't completely stamped correctly, or it had faded...Just reporting the date code on the package. I'm not speaking for the accuracy of that.
