There's no mystery to the 10mm. I've got a boatload of them, including semi-auto pistols from Tanfoglio and Colt, a revolver from S&W and a 10mm AR carbine from Olympic Arms. I just sold one of my Colt Delta Elites, so I'm just down to one Colt in that caliber now.
I would stick with the 180 gr. bullets, since that's about the most common loading anymore, and there's plenty of data available. The 10mm was originally configured with a 200 gr. bullet, at 1,200 fps, but some configurations (Glock) don't fully support the case and you end up with guppy formed brass after shooting, which ruins the brass, so most loadings are less than the original Norma load.
And yes, your Tanfoglio is going to send your brass into the next zip code, so if you can possibly shoot next to a wall, that will keep the brass from flying quite so far. You can also shorten the ejector like Seismic Sam did to his pistol. It's a sticky on the Clone Forum, and here's the link:
http://www.czfirearms.us/index.php?topic=8209.0 Shoot your new pistol and break it in properly before attempting any modifications, though, which I suggest with any new firearm. Too many people modify firearms before ever shooting them, so they don't know if the original configuration was right for them, or not. Then they report problems with their "new gun" and don't understand why....
Starline makes 10mm brass, and it's in stock, and most any 180 gr. bullet in .400"/.401" diameter is going to work in the 10mm. Some nose configurations work better than others, and each pistol is an individual.
You're LnL press will load 10mm until the cows come home, so don't worry about it. There's a ton of reloading information available for the 10mm, too.
I personally don't care for the lighter loads in the 10mm, especially with the 135 gr. bullets. They go fast, but I've never gotten the accuracy out of the lighter bullets that I get with the heavier bullets. In fact, my most accurate load is with a 200 gr. cast bullet that I cast from an RCBS mold. It's proven itself in both the pistols and the revolver, but I don't shoot them through the carbine. I'm running them hot and I confine the carbine to fully jacketed bullets. Even plated bullets won't run through the carbine, since they end up well over 1,450 fps and tumble because they've stripped the rifling.
Hope this helps.
