Re: firestorm .50 cal load?
Simply my take on it, but I think if you are using 90-100 gr. of 2F in the pipe, you are hitting on the heavy end of a charge load for a 50 cal. I load 80 gr of 2F, but I'm shooting PRB's too. Also, though 3F will be less succeptible to dampen in the pan compared to 4F, I think 4F may give you a better chance of proper ignition consistently... especially on a "dry"/low humidity type of day. Guess it's all preference.
