Okay so I think I'm finally going to order some of these things. My questions is, how do you know what loads are safe with these bullets? Normally when reloading you have a manual to guide you. With these, I see they are handgun bullets, but how do you know if they will be safe with your powder charge or not? I'm planning of shooting 100 grains of Pyrodex. Will this be safe with the 300 grain deep curls? In a muzzle loader, how can you tell signs of too much pressure?
