[QUOTE="boomtube, post: 282639, member: 9215"] I believe people who have the most problems with Lee collets, and perhaps a lot of other Lee gear, is due to a burning desire to do things by the numbers rather than the results. A properly used Lee collet neck sizer is a god-send to those of us who seek best accuracy with factory rifles, IMHO, but it can't be set up very well by a specific set of directions, a lot of it is by feel and that varies by the press. And the user! It makes little difference if the press cams over or not, if the collet die is adjusted to the right point it will work quite well. It seems that many buy it with the errouneous idea that it must work much like a common neck die so it needs lube. Or that, in some obscure way, if they push harder on the press they can increase neck tension when all they will do is bust off the top cap, which is made of fine threaded aluminum to strip and keep such users from busting the die or his press! Many users seem to hate that bullet tension with a collet die is frequently quite low. They don't understand that high bullet tension is a large contributer to bullet run-out (actually, the pressed fit of a bullet into a too small hole is not quit the same as "tension"). The lightly fitted bullet held in a collet-sized neck helps maintain good neck and bullet concentricity for some really good ammo! Cases sized with the collet dies tend to shoot better with bullets seated well out. The BR practice of seating near or into the lands is mostly helpful to achieve good powder combustion with soft seated bullets, not so much to "align" them to the bore as many think. Done right, crimping can also help obtain better combustion in factory rifles when using a collet die. [/QUOTE]
