Hmmmm interesting! Never shot 147gr in my 9mm. How's recoil compared to the124gr? Would imagine it would be less snappy. What powder do you use! SNS seems like a good source. Do they charge shipping? Notice they charge tax. Have you ever tried the "red" coated fodder? Sorry for all the questions... 
I use 147gn for my SD ammo, so I wanted a similar load for practice. Also, I was contemplating using this for getting into competition, so less (snappy) recoil is a plus. I never chronographed the load, however, it "feels" about right to me and POI is the same as my chosen Winchester Train and Defend "D" defense ammo.
The reloads, and defense ammo, is subsonic so it is a little less loud. I don't think the color of the coating matters much. They don't have the red coating on the flat point bullet profile. I wanted the flat point profile because it's shape is very similar to the shape of the hollow point. The coating is said to make the bullets more slick in the barrel so higher velocity, lower pressure, and less powder is required for any given specific velocity requirement.
I deburr the case mouths to keep from shaving the coating when reloading, however, If I get lazy, don't deburr, and it shaves a little bit of coating, it doesn't show any effect of the loads, target, or cleaning the barrel, as far as I can tell.
I'm using 3.2 grn of Bulleye, and what ever cheap small pistol primer, currently CCI. They charge $15 Priority Flat rate, I can remember if I requested that specifically. They don't charge tax.
