Thread: Powder: How old is too old?

There you go - (not my words but certainly my understanding)

H414 is the exact same powder as W760. Essentially Hodgdon was buying W760 from Olin (Winchester) and relabeling it. Now that Hodgdon owns Olin they dropped the H414 name. Data is 100% interchangeable on every reloading manual I have ever seen.11/12/2020

There are also suggestions that very early on (longer ago than 15 years) that there may have been difference between them or differences between earlier lots of W760 and the later lots. Same old warning still apllies - work up.

I have one rifle that I load for using W760 and I'm a fan.
