Sure it will function, and it's probably a very accurate load since PP is probably the best 9MM powder, I just don't think your velocity readings are accurate.
I discovered 6 grains about 7 years ago, and to this day, have never experienced a more accurate recipe in 9MM with 124 grain lead round nose bullets and the Win SP primers.
I'd check with another chrono just to verify it. What one are you using now ?
I buy my bullets from mastercast for about $50/1000, and get no leading and no smoke whatsoever .... I use mastercast bullets in all my autos.
By the way .... by WAY OFF, I meant probably about 100 fps from your 1100 number.
