I've got 6 mags for each pistol and have 2000 rounds of brass on order from Starline. Getting the bullets I want are going to be the big problem. I can't afford to load a huge number of the Lehigh bullets as they are pricey, to say the least. What I want are the 165 Speer Gold Dots, my second favorite bullet. I like the velocity possible out of the 10mm and it's high enough to insure they operate as advertised. I don't know if Federal sells the HST bullet as a component (they don't) so that would leave the Golden Saber. I've already tried a few of the Hornady 155's and while they didn't seperate the core & jacket like the (older) 9mm's, they do fold the petals back along the shank of the bullet at 10mm velocities, so I may try slowing them down some (against every fiber of my being!) to see if that works. I suspect they are optimised for the 40S&W. We'll see what turns up but somehow I don't ever see the Lehigh bullets coming out "on sale" from anyone! I can use either the 100 gr or the 115 XD, but I think the 100 is the optimum bullet for the 10mm. I have some and once I get a red dot for my G29 I'll do do some bench shooting to see if there's a preference.
If it is the Hornady XTP they are designed for "limited expansion" so they can get a couple extra inches of penetration. The XTP is the last round I would use for DS.
