[QUOTE="MudRunner2005, post: 980270, member: 12995"] He may not need to FL size every 3-4 rounds. But sometimes the brass can work-harden and loose elasticity with a fat out of spec factory chamber (possibly), and might be tough or tight when pushing the cartridge in or extracting after firing. And sometimes a FL is all it needs to get another couple firings out of that brass. I wasn't give him a specific order, just a guideline. This scenario was what I had to do with my STW brass because it has a very generous factory chamber girth... But I haven't touched the rifle because it shoots so **** well, I've learned to work around the issue. Now, my custom 7mm RM's have been reamed with a custom reamer ordered to very tight specs so the brass doesn't grow much. I haven't had the first sign of needing to FL size in over 3 firings from new Nosler brass. And it barely has any width growth above the belt/web area because the reamer tolerances were so tight. Ejects like a dream everytime, even when loaded hot. [/QUOTE]
