When sizing cases it is said that you need to size the case inner dimensions at least 0.002” less than caliber as to maintain a proper tension on the bullet. Some experienced reloaders say you must throw out the expander/decapping rod when resizing since it tends to throw out the alignment of the case neck. This is working very fine with my .222 Rem since the sized case is between 0.002” and 0.003” under caliber after sizing. I have tested load on this sizing technique and could not find any difference in pressure or grouping of the .222 Rem. However, when it comes to my .270 Win it is a totally different story. When I take out the expander/decapping rod, it gives me a measurement of the inner dimensions of up to 0.007 - 0.008” smaller than caliber. I use a Lyman VLD deburring/camphering tool. My question is whether the tension is excessive and what influence it would have on consistency of loads?
