The bank holiday has finally provided a chance to start attempting to reload. I'm starting with 150gr Sierra HPBTs for practice as I haven't yet managed to obtain those DL1 bullets from France. It's August, and France is closed. Yesterday evening, I set about measuring the OAL by partially setting a bullet and adjusting it in the rifle, so now I should have worked out the ideal length for this bullet and my particular rifle. It's noticeable longer than any of the factory loaded rounds I have. If you have a look at the picture below, you can see my FMJ dummy round on the left. It is 72mm long. Left are three Federal rounds. The first is a 140gr Nosler BT, then a 140gr Fusion, then a 150gr Speer HotCor. They are respectively 70mm, 70m m and 68mm long, all noticeable shorter than mine. Makes sense for a factory round I suppose, it's erring on the side of safety. So here I find my first major difference between reloads and factory rounds. More on this as I progress through the day.
