Looking over the 10mm I have on hand - factory loads - found Underwood 200 gr JHP, and Buffalo Bore 220gr HC. The Underwood claims 1250 fps on the box, the BB says 1200 fps. Right now I have an RIA 1911 and two EAA Witnesses - one blued, one "Wondra" finish in 10mm. Would like to try a Sig 220, as I have one in .45 ACP I really like. My handholds are normally a bit "slower" than these factory loads. I am a BIG fan of 10mm in semi-autos as a woods-hunting gun, and I also tend to prefer heavy HC lead bullets. Some time back, I had a problem with some Double Tap ammo in a Glock G20, otherwise 10mm has been "good" for me, both factory and handholds. I have tried Power Pistol, Universal, Unique, and Titegroup powders with no problems.
