[QUOTE="boomtube, post: 335390, member: 9215"] A few questions: Have you tested the sized cases for RO before after resizing? If not, do so, both with and without the expander in place. No seater can make straight ammo if the necks are cocked out of line. The Lee collet neck die makes the straightest possible necks for factory rifles The Lee collet die also tends to make for less "bullet tension" and that allows bulelts to enter the necks under less prssure so they will seat straigther. You say RO is .020". Is that a range or are all all of them that bad? If not, what's the full range of RO, min to max? That's so bad it suggests you have some cases with badly non-concentric inner and outer diameters. No die will fix that either. Do you have a case neck turner? If so, you can do a LOT for RO just by shaving a bit of the worst parts off the outer surface. Have you asked to borrow dies from someone else to compare how another set may work with your brass? Asking for suggestions of what to try allows us to plug our favorites but it really doesn't mean anything. All of our die makers do good work and all of them turn out a few turkeys. Fact is, on average, there is as much variation between individual dies of the same maker as there is between makers. Brand or price tells us only the brand and price. The only way to KNOW what any given die will do is to use ita and test the results on a concentricity gage! The double exception to that rule on dies, again on average, are the BR/Competition dies from [B]Forster[/B] and [B]Redding[/B]. Forster has perhaps the better size dies because of the way their expander button works, and that works better only if it's adjusted properly. The unique straight line, full case holding sleeves used by those makers seaters are the same so there is no advantage between them for that. NO other brand of (non-custom made) "competition" dies are worthy of the name, regardless of price. IMHO. And from testing a lot of dies. [/QUOTE]
