Ok I bought 500 pulled 180grn hst's on Rocky Mountain reloading the other day and was trying to find a load for them. I have found a load on hogdgons website that is for horns day xtp's. Could I use this recipe and just substitute the hst for the xtp? This question come up quite often. The first thing you need to understand is that Load data is Not a recipe. It is merely a guide to get you started, that is why they have a "Start" and a "Max" charge. There are way to many variables for data to be an absolute and a recipe. You could never duplicate the data from any manual even if you wanted to. To do so one would need to have identical components and Identical conditions. Not only would the components have to be the same brand and type they would have to be from the same Lot number as well. Totally impossible. Lets not forget the number one component of all, The Firearm. To treat Load data as a recipe you would have to have the same firearm that was used to gather the manuals data, not one just like it, the exact same one. Now that you know that load data cannot be followed to the letter as if it were a recipe, the answer to your question is rather simple. Find as much load data as you can with Same Weight bullets of Similar Construction. Similar construction is Copper-to-Copper, Lead-to-Lead, Jacketed-to-Jacketed. Then Start low and Work up. Also OAL is Always firearm and Bullet specific, never manual specific. You must find the OAL the fits-feeds-fires in your pistol. After all if it doesn't fit-feed-fire, then there is no need to worry about pressure. |
