I got a email back from Buffalo Bore and he said that he carried a Kel Tec most of the time and he used the 100 gr hard cast flat nose at 1061 fps out of his Tel Kel. He said they hadn't had any problem with any of the 3 loads. I thought I would get a box and fire a clip and see how it does and what kind of recoil it has and if everhthing is ok, I may use them to carry.
