JMHO, but if you're getting good groups with the rifle with that powder, it's very likely you'll get good groups with other powders as well.
There's very little to no difference in several of my guns with 3-4 different powders.
Both XBR-8208 & AR-Comp are truly top notch accuracy wise.
As are MR-2000, Varget, RL-15 & sometimes H4895........some may not give maximum velocity, but all are generally very accurate in most guns.
Sometimes you need to find the sweet spot in the charge weight to get best accuracy, but it's really not much fun to have a gun so finicky as to "have to have" only one particular powder to shoot well...........I really don't much want to have those guns. Truly good guns are usually not that finicky, whether they be AR's or bolt guns.
