was it a service powder or made for reloaders? and if it was mad for the army what did they use it in? thanks!-Travis

IMR4895 was formulated to load cal. .30 Ball M2 during WW2. Hodgdon Powder got its start selling surplus 4895 in brown paper bags. H4831 was salvaged from pulling down 20mm Oerlikon cannon ammunition.
boy I would love to have one of those!
I used to buy it at Viking Arms on Reno St in Oklahoma City for a quarter a scoop back in the 60's. Did all or my rifle reloading with it and still use it today.
I got the impression that it was developed around making the .30-06 cartridge launch a 152gr. FMJ bullet at 2800 + 50 f/s in the M1 Garand rifle, without bending its operating rod from excessive port pressure. In the process, it proved to be a rather versatile rifle propellant. It was also my impression that another company that was contracted to provide propellant for the same application devised a propellant later known as IMR-4064, for the same purpose, but I could have that wrong.
I started using surplus Hodgen 4895 in 1959 when it was $1.25 for a one pound can. I could also buy original Ball C at the same price, but I didn't like it as well.It is a very versatile powder. I still use it, but in the IMR label.
I used it in the early 60's and would still use if the need arises,I am down to using tightgroup for all my loading now.One powder for everything from 380 to 45C
IMR 4895 is my ONLY powder for 30 caliber loads and it works pretty well in some other applications.
I used other powders but always came back to 4895 and eventually just stopped wandering around and settled on 4895. That was many years ago.
I cannot intelligently answer the OP's question but I happily yield to Outpost75's knowledge.
Sorry to get off track,but is H4895 the same stuff?
H4895 is pretty much the same as IMR4895 but is just a tudge faster burning in most top end applications. With cast bullet loads there's not much difference at all. H4895 is smaller kernelled and meters through powder measures more accurately. H4895 is also an "Extreme" powder so it is less susceptible to temperature variations. H4895 is made in Australia. IMR4895 is made in Canada.Quote:

Thank you for the explanation. You are a wealth of knowledge.Quote:

no they just moved production of many AADI [Australian defense industry's] powders to Canada.
their burn rates slightly changed as did some of the colors of the powders.
Will help w/ availability but it makes things even more confusing when it comes to Hodgdon's line of powders. It's why I stick to a select few, most of which are made by St. Marks.Quote:
