dies neck or full length

[Catfish]

I am a neck size fan. I very rearly FL resize and have loaded alot of brass than was fired till the necks split without it ever being FL resized to set the shoulder back. But then, I don`t shoot semi-autos, only bolts and break opens. I also shoot several custom chambered rifle which tend to shoot alot better when neck sized only. Benchrest shooters never FL resize, or at least I don`t know any that does, and group size is their only goal. I find that unless I`m pushing the presure limits that I almost never need to FL resize my brass unless I`m going to fire it in a different gun.
