I experimented with reloading accelerators many years ago when I picked up a box at a gun show. What I found was the accuracy of the 22 caliber bullet was equal to the 30 caliber bullet.
In other words, If a rifle shot 3 inch groups, the accelerators would shoot 3 inch groups. I tried them in both 30-30 & 30-06. Unsatisfied with the results, I abandoned the idea altogether.
Why would you expect anything else?
Frankly, that BEATS the expectations I'd have from reports I've read.
In any case, there's no reason to believe that making a .308 cal gun shoot .224 bullets is going to make it more accurate. MAYBE the same accuracy but even that's debatable. I can't imagine the rationale to expect IMPROVED accuracy.
To the OP, if you don't already have the supplies, EABco sells all of it and they have a pretty good amount of load data too.
