[QUOTE="boomtube, post: 245917, member: 9215"] The question of accuracy vs. neck sizing is just that, a question. It can only be answered by experimentation in YOUR rifle! IF a case is FL sized [U]correctly[/U], NS frequently adds no accuracy benefit for factory sporters but the brass may last a little bit longer. You can't do better than the Lee collet neck sizer but it does have a learning curve, if you aren't willing to take the time and make the effort to learn to use it, get something else. There will be no "doughnut" problem at all. And I seriously doubt you would see any advantage to a more expensive custom die for a factory rifle. A set of Foster BR dies, FL and seater, are about the best option you have for max accuracy in our type rifles. Forster's FL sizer has a great expander ball system. No other seater die is better for a factory rifle, most others aren't even close. The micrometer seater head option is nice to use but it really doesn't make the ammo any better. Look at [URL="http://www.sinclairintl.com"]www.sinclairintl.com[/URL] for them. Strickly speaking, a neck "doughnut" is a thicker ring that developes at the neck/shoulder junction when reforming a large case to a smaller one and is hard to remove by neck turning so it requires reaming. It's really not related to neck sizing, as such. The amount of case neck bulge below where a neck die may stop is not thicker so it has no impact on bullet tension or safe release on firing. [/QUOTE]
