[QUOTE="abinok, post: 66409, member: 16"] 4Ked, I just take of the snags, all im after is a square edge around the hole. Its worth noting that chamfering the hole does nothing to cause pressure indicators in my experence, but enlarging flash hole diameter does. Its also worth noting that even this does not actually change the pressure, but only increases the apparent pressure due to the primer seeing a larger surface area of the same pressure. Whoops, I missed primer pocket uniforming, with a good tool (as was said), you can clean the primer pockets with the same tool, since after cutting the depth, carbon is taller, and gets cut on successive loadings just like brass in the initial loading. As for neck thickness, both. I will cull cases if they have more than .001 variation on a single case, or if they are consistantly within .001, but markedly thicker, or thinner. I set up my loading block and go through it just as if I was laoding them, left to right, top to bottom, and write on a sheet of paper what the max thickess is. Then after I have done 50 pieces, go back and look at what the most common thickness is, and cull the extremes. With my favored 300WM LR rig, I use only Federal brass, and it is very consistant. Out of 100 pieces, I rarely cull more than 2. After im out, ill likley go to Lapua... well see.... As to your expander question, 1. How are you lubing your cases? 2. How are you lubing the case necks (inside)? 3. How many finings? 4. What dies are you using? [/QUOTE]
