Quality Powder for 45: VV-n320
Nobody has anything bad to say for it.
Meters smoothly
High velocity to pressure ratio (i.e. efficient)
Consistent performance for tight groups
Minimal flash/smoke
Pretty much everything you could want in a pistol powder in the 9mm-45acp range.
Except the price. Quality is expensive (not hard to get), expect to pay 50% more. Places which carry it, always have it in stock. Places that don't, never do. Go Powder Valley and buy in 4lb chugs up to the weight limit for a single hazmat fee, and include your primer needs into a single shipment. Then it aint so bad.
Why go through the hassle of having to buy in bulk and spend more than run of the mill powder? Back when I was a shooting nut, I tested up to 11 powders that various forum threads recommended. Got tired of trying this and that and looking for something better. Somebody said, nobody ever turned away from N320 for something better, and some things are worth paying 50% more, especially if you look at the total package when its all done. I found that to be true.
Good luck and welcome to reloading. I hope you got the classic cast turret and not the regular turret. That's a great beginner press. Pay attention to what people say to avoid screwing up the advancing mechanism.
