Question Shooter's World powder data Needed

Trying to work up a load for my Yugo M-57 in 7.62x25 Tokarev. I found an old thread, but nothing really relevent to what I am doing. Hoping that someone may have some experience using this powder and the heavier than normal projectiles. Having accumulated all available loading data from Lovex and Shooter's World and not finding data for my application is a little frustrating.
Here is the situation:
I have secured some Armscore 110 grain FMJs, .308 dia. bullets(.30 carbine pill).
Will be using CCI small pistol primers and Shooter's World(Lovex) Ultimate Pistol powder(D036-07).
Tried some loads the other day @ 4.6/4.8/5.0/5.2 grains of powder and was surprised that every load cycled the gun. The OAL was 1.320". The heaviest load felt a little over powered, but there was no signs of over pressure on any of the spent cases.
After testing, I decided to take the average of the test loads and do a batch of 50 using 4.9 grains of the powder and an OAL of 1.360". This matches the length of some factory loads in my possession and should insure that pressure stays well under maximum levels.
I do not have a chronograph so my testing is based primarily on the way the gun feels compared to factory or surplus ammo.
Picked up this powder recently and must say it is the finest I have worked with and it is very easy to double charge a case so double checking everything is important. Meters very well, but you may need to work on your powder measure to keep it from leaking out while charging cases. Finally got one of mine now dedicated to very fine powders after smoothing the internal surfaces to minimize any gaps which could allow leakage.
These bullets go far into the case and are below the case neck when fully seated.
Looking for input from the collective. Am I missing anything critical? Anyone have a recipe for this powder and comparable projectile in 7.62x25?

Did you try emailing Shooters World from their webpage?
I did and got an email back the next day from Ken Johnson with recommendations for M1A loads. Ken Johnson is their head of ballistics and was previously at St Marks in R&D. He was an Instructor at AMTU when he was enlisted in the Army. He may just point you to one of their one of the other powders that is "similar to" Accurate numbers, but he will answer you.

That is something I had not considered. Thanks for the suggestion.

Intending to try some of my test loads tomorrow. Seabee gave me some helpful information that indicates my loads are quite light. They cycle the action, and if they are reasonably accurate, I may just keep them that way for safety. The range is short, but if they hit the center of the target and group well, that will make me happy. Just looking for a safe plinking round.

Please share your developments. I've always stuck with Unique because I have it, there is published load data, and it does everything. I might try the SW powders when this last can of Unique runs out. I have Clays for shotgun and some other pistol rounds, but i think it's too fast for the Tokarev.

A question for you: Do you make cases from old 223/5.56 or just buy PPU or something and shoot it then reload it?
I did the 223/5.56 for a hundred cases and think I'd rather pay for new cases than waste all that time again.

Back in the eighties I made ammo for my Tok bringback. What a pain in the butt! The worst part was that they had to be reamed so they would chamber. I don't remember the load I used but I used to put a 12x12 tarp next to me to make sure I found all the empties.
