The powder is probably not too far off from the 4895s based on how much is in the loaded rounds and comparing it to Hodgdon's data for 150 grain bullets in 7.62x54R. You are unlikely to blow anything up if you start low and work up using 4895 data for .223.
Reloadng is like cooking. You don't always need an exact recipe if you can apply general principles and guidelines.

Won't have results until Sunday, unfortunately since I'm camping can't see if it will cycle my Ar.. But will have a t97 with me different animal but will see if it cycles.. One thing I am expecting is this powder to be real dirty..
Starting with 3031 loading data is safer for those involved. When the first batches of Finn surplus arrived at International many years ago I bought a pallet of it. It was in short supply at the time for the SVT 38s and M91 variants that had arrived a few years earlier at $19.95 each. They were loaded with the same powder that the surplus 160gr Swede 6.5x55 cartridges came with. That powder was Nobel #44 which was interchangeable with 3031. The Russians had quite an influence on the Finns and likely most of the other nations in that region of the world. The Finns used captured Russian equipment and ammo regularly and likely on an interchangeable basis depending on what was on hand at the time. It only stands to reason the Finns would use a similar powder. They used Nobel #44 as it was as close to the powder used by the Russians as they could get.
I liked those Finn surplus 7.62x53R because they had non mercuric/non corrosive primers.
I'm not saying the OP will even get close to a dangerous load with 4895. I do however feel it's burn rate is to slow to start with. This is my reasoning.
The starting load for 3031 is 21 grains. The start load for 4895 is 23 grains. In a larger case and larger bore 2 grains doesn't mean much but in a small 223 case with a 224 bore, things add up pretty quickly.
Likely I'm being to cautious. Still, I have pulled thousands of rounds of 7.62x54R and repurposed the components. For extruded nitrocellulose powders I have always used 3031 data as a starting point.
When it comes to pulling components from midsize cartridge cases to use in small cartridge cases I prefer to err on the side of caution. There is enough difference between the two powders to warrant this IMHO.
This video is all about developing a load using a powder lacking load data.
OP: Any results yet?
Find at the range alot of ppl who reload are just a one or two caliber kind of person, then there is me and another guy pulling all the brass we can find out of the scrap buckets... Lol
