I was able to score 1K 62 Grain steel core penetrator FMJ. I have H4895 and H-335 powder and both magnum and standard primers to use. Which of the powders I have would your prefer and do you have a favorite load for either? I have a couple thousand mixed brass cases and about 1K speer nickel 223. Should I start sorting through my brass and use military brass or should I stick with the nickel speer? Thank you!
