[QUOTE="Gus McCrae, post: 964979, member: 66278"] Instead of starting another thread, I'll reply to this one with a problem I may have. I measured a couple of cases, from the loads I shot today, with a Hornady Cartridge Headspace Gauge. The unfired cases measured 2.087'' - fired cases 2.100'' for a difference of 0.013''. This sounds pretty excessive too me. What is the best way to remedy this? I have quite a bit of brass that's all been fired in either a completely different rifle or this rifle but different barrel/chamber. Do I need load all of these cases with a low-middle powder charge and fire form all of my cases before stepping up the dose? I had one primer that looked flattened, but the rest of them looked ok (edges still rounded). Any help would be appreciated. Edit: I went through all of my 280 brass and measured 4-5 out of each batch (varied from 2-4 fired brass from the previous 2 rifles). Those all measured right at 2.094'' (+/- 0.002''). I have one batch of virgin brass that has been full length sized and it measured 2.097''. It looks like I screwed my FL die down too far and bumped the shoulders back way too much on the batch I shot today. I'm not sure what to do with the 28 rounds I didn't shoot today. I'm thinking tear them down, back off the powder charge a grain or 2 and fire form them. [/QUOTE]
