Burn rate IIRC for Staball is close to H4350 and that would seem better for the cases with a bit more case volume. But if you have it give it a try and let us know.
I could be wrong but I think it might be a case of diminishing returns especially with the lighter weight bullets, which I have seen a few times for cartridges and slower burn rate powders. I suspect it will not get good burn without being near the high end of charge weights and that is something I shy away from with the AR platform generally. Keep up with velocity in the ladder test and look for plateau of velocity as powder charges increase. I think with the lighter weight bullets you might run into that.
Like I said earlier if you have it give it a try and let us know. Curious to see the data. People did say CFE223 and Leverevolution were to slow for the Grendel and they work fine.
yeah deff needs the heavier bullets but i have no use for theese 90 fmj's soi figured perfect bullet to waste for fireforming , same with the staball i have a lifetime supply of that stuff for my creemoor so instead of using up my good arc/gren powders to fireform i figured why not use the staball but after that round of fireforming ill see if i cant make a decent sd load with it and those 90's or maybe even just plinking ammo
