I was able to get 2300fps with the 129gr and 2250fps (before seeing pressure signs) from the 127gr. Both with CFE from a 16" barrel. I was limited to mag length while I still had plenty of length to lands left. I imagine 8208 would be to fast for these. AA2520 may be worth a try especially for the LRX.
I think the 129gr loaded out beyond AR15 mag length restrictions would produce significant increases in velocity.
