"H110, W296 These two powders are very interesting, and I use them both when working up hotties in the +.400" bores."
I hate to tell you this, but they're the exact same powder. Made in the same facility on the same production line. The labels reflect who bought the batch.
I always thought that they were slightly different, different deterrent coatings and the such, but apparently not.
Any differences in performance are probably just cannister/lot variations.
