Man, I wondered the same thing... first magazine I loaded was brutal on my thumb! After leaving it loaded for a while, I emptied the JHPs and refilled it with FMJs at the range... and they went it way easier. I guess it loosened up enough, or maybe my technique was better. In the meantime I had ordered the Uplula speed loader... I tried it as soon as I got it and it's almost too easy when using it! haha
