I just acquired a beautiful FN49. Has anyone here ever developed a load for one? I'm currently using the same load I used with a Yugo Mauser I had (46.5 grains of IMR 4064 with a 170 grain bullet.) I'm wondering if a faster powder might work better. The gun has a gas adjustment, but I'd prefer not monkeying with it if I don't have to. Thanks in advance for any insights.
