Reloading using primed steel case

[Rottentofu]

Just got a bunch of primed steel case of 7.62x39. Is it safe to use the same powder data used for brass cases for steel cases? I plan to use H4895 and Hodgdon website shows starting powder load of 27.0gr.

I am purely speculating here (also tried Googling, but found nothing substantial), based on what I have read before, steel case expands at a different rate than brass case. Will this make it unsafe to use the same amount of powder prescribed for a brass case in a steel case?

Some company actually sell primed steel case ?

TL;DR - I don't know

You have a few things going on. First, you need to have enough pressure to expand the case and seal it in the chamber to prevent blow by. Secondly, that impulse needs to be long enough that most of your powder has burned before the case retracts. Thirdly, it needs to be gentle enough that the brass or steel retracts a bit after burning allowing you to pull it out of the chamber.

Steel is tougher than brass, at a guess I would suggest starting at the lowish end for your bullet weight and working up until you don't see soot around the case neck and you don't have any failures to extract.

That being said, I'm not a lawyer, and no one said I was good at reloading.

I habe reloaded steel using brass data with no problems.

I'd try 1,000 steel primed 7.62X39 AK cases one time. Maybe 54R Mosin Nagant steel primed cases as well, once. Depending on price of course.

Special Note To Handling Steel Cases:
I was practicing reloading the internal magazine on my former M39 from a 5 round stripper clip. After load & unloading the clip, for the 900th time, I got a mother-of-all steel sliver off a steel cased cartridge. Poor me I know. I can hear the violin playing just for me.

Be mindful of possibility of corrosive primers and clean appropriately.

Thanks for the help guys. I will start below starting load just to be safe.

I bought several thousand primed steel 223 cases a while back. Bulk loaded them with middle of the book 55grain fmj loads with several powders. They all shot flawlessly and were just as accurate and precise as M855.
