[QUOTE="J E Custom, post: 1510740, member: 2736"] I realized long ago that dies are not a perfect match to the chamber unless they were reamed buy a sizing reamer of the same manufacture as the finish reamer and even it is not a perfect fit. A fire formed case is as close as you can get and a neck sized case is very close except for the neck because it is sized for bullet grip. Leaving the die set for neck sizing and using a shell holder that is .001 or.002 thousandths thicker is a good way to do a controlled bump. I have over 50 die sets and over the years I have included a shell holder in each set so the sizing process would not change. For my set up, when a cartridge starts to get tight on closing, I use a feeler gauge between the case head and the shell holder. I start with .001 gauge and go up from there until I get the fit I want. (I only want to reduce the area that is making the case tight). Once I see what it takes, I replace the feeler gauge with a small piece of shim stock the same thickness and the size of the case head and hold it in with a dab of grease under it. This way I can adjust the amount of sizing required to do a minimum sizing using the same die. The amount of sizing required increases as the cases get older so this method giver me the flexibility I need. Also if you load a large number of cartridges you would need two or three different shell holders for each cartridge to get the benefit of this method. I like the shell holder method a lot, but for me it would require a bunch of shell holders for each cartridge and brands of cases (Thickness and toughness have an effect on how much sizing is required). I am not a bench rest shooter, but think like one and my mentor was one so I will test everything that may/could help me, and I have developed what works best for me and my loading process. others have there own way of loading precision ammo, but this is just the way I do It. Lots of good information to absorb and most of it very good. J E CUSTOM [/QUOTE]
