So I have a partial box of handloads from the older gentlemen i bought the gun from, new brass and 140 grain bullets using RL 19 powder was his recipe, with this powder shortage etc. going on I have H4895 and H414, as a starting point, go to the charts for the RL 19 and estimate velocity, then try to duplicate that velocity with the powders I have available, is this a logical approach or has the turkey got my mind sleepy? LOL
