I'm bringing in some powders for re-sale that I don't have any personal experience with and was hoping to get users opinions of these powders: If you have used any of the following will you please post up your experiences. What caliber(s) you use it for, how does it meter, etc.
I'm tired of googling and would like to hear first hand experiences. Thanks.

Winchester AutoComp
AUTOCOMP is extremely fine in the 38 Super, 9mm, 45 ACP and 40 S&W race guns. It’s just the perfect burning speed to feed the compensators with a higher volume of gas. With AUTOCOMP competitors get off faster shots with minimal muzzle flash, it’s a winner.

IMR 4320
Short granulation, easy metering and perfect for the 223 Remington, 22-250 Remington, 250 Savage and other medium burn rate cartridges. It has long been a top choice for the vintage 300 Savage cartridge as well.

IMR 4831
IMR 4831 has a slightly slower burn speed than IMR 4350. IMR 4831 gives top velocities and performance with heavier bullets in medium-sized magnums.

IMR 4064
The most versatile propellant in the IMR spectrum. 223 Remington, 22-250 Remington, 220 Swift, 6mm Remington, 243 Winchester Super Short Magnum, 308 Winchester, 338 Winchester Magnum and the list goes on and on. Versatility with uniformity and accuracy.

Doug,

I have used a lot of 4064. 30-30, 308, 30-06, 7X57, and 7mm-08. They all seemed to be good, consistent and when I did my part. they all shot - M.O.D.(minute of deer) for accuracy. Harvested a fair number of deer and elk.

43.5gr of 4064 topped with a 168gr SMK is my .308 bolt gun's favorite. (Essentially Federal Gold Medal Match) Also good for .30-06, as Cootduster stated. Comparable to 4895 in performance, but has different load data, anywhere from 0.5-1.0 grain difference in load requirements for the same velocity when loading .30-06 for my M1 Garand.

4831 is readily available here in Aberdeen, Bi-mart gets it in but not a lots of folks use it. Picked 3 pounds up this week. I use it along with 4350 for my .300 Win Mag loads. Good performer.

4320 I've only ever bought one pound when I couldn't find 4895/4064. Worked well, just had to work up a load for it.

4064 is an excellent powder. I have read that the military is or will start using 4064 for 308/175 sniper rounds, as it's much less temperature sensitive than RL 15. The only problem with it is that it is hard to meter due to it's size, and could involve a lot of powder trickling if you don't have something like a chargemaster.
I use it for garand loads and 30-06, but I may start using it more in 308 and 5.56 as well.
