[QUOTE="Buffalobob, post: 88381, member: 8"] Second question. If I understand the indents, these are caused by having too much lube on the case and it getting into the shoulder area of the resizing die and having nowhere to go. The trapped lube will form dents in the shoulder of the case. As long as you are not shooting over max loads I wouldn't worry about them, becuase they don't decrease case capacity much. Three things to do. Don't use much lube on the neck and none on the shoulder. Check and clean out the "lube squeezing out hole" because it may be clogged or it may be under the set ring. And finally take the die apart and clean it real good to get out the trapped lube. Fireforming usually refers to a wildcat cartridge that is made from another cartridge and must be fired to get it to expand out to the new chamber dimensions. If the differences are small then you can use a pretty good charge of powder and get pretty good accuracy. You will notice that SS7mm killed a deer and an elk at impressive ranges and for the deer extreme accuracy. For cartridges where the new chamber dimensions are greatly different then you will use a very mild charge that is just enough to expand the brass. Sometime a person will take a brand new piece of brass and load it at some type of reasonable speed and shoot it once. That piece of brass that is now chamber size of the gun is then worked over and neck sized or partial resized and loaded up. This gives the case a very good fit to your particular chamber so you get more accuracy and you also can cram more powder in it. Too slow typing -Agree with what Jerry said [/QUOTE]
