10MM in a Star Megastar?

What is a good load for this really heavy gun? Let me clear this up a little. If you own a Star Megastar in 10MM, and if you reload in 10MM, what do you like?
I have about 600 bullets that are 180gr FMJ made by Winchester. What is a good powder I should get for it? I have 2400. From what I have been told, this gun can handle some really hot rounds. Anybody know how `hot', hot is? I found some data for the S&W 610, that was really hot. I got some 10mm from georgia arms, and they seem kinda weak. 180gr @ 1100 fps? Just seems kinda `soft' to me. I know there are faster burning powders, what is a good one? What do you guys think of Double Tap ammo? There is a gun show soon, so I'm making a shopping list. Thanks, Matt

Here's a link to loading data that did not necessarily come from the component manufacturers. USE CAUTION WHEN TESTING!!!
I have found with a 180 grain FMTC Zero bullet, that I like 8.2 grains of Power Pistol with a Winchester Large Pistol Primer. That's in both my EAA Witness and my Fusion Commander Length 1911. Max for the powder is 8.7 grains.

One-powder choice for 10mm = N350

Then, after you get some, e-mail direct for safe 'hot' data.
