I made up ten cartridges today with 49gr IMR 3031 and a 405gr HB lead bullet. Didn't notice untill i was done loading that this recipe was intended for a 400gr JSP. I'm shooting a Shiloh Sharps....Too hot a load for the Shiloh? Time to knock these bullets out and load again? Is there a big difference in pressures between lead and jacketed bullets?
Thanks for any advice..... I need to get the Lyman book!
