[QUOTE="RT2506, post: 1131146, member: 10178"] Get a Lee Factory Crimp Die and leave your cases 5 thousands inch longer than the trim to length. This will give you enough case to get a good crimp on. You do not need a bullet with a crimp groove because this die will make it's own. From my own experience this does not destroy the accuracy of the bullet, even match bullets. One other advantage of this crimp I have found is that you don't have to go through that find the lands and "proper" seating depth process. The crimp holds the bullet in the case long enough to allow the pressure to build up for a good consistent burn and I have gotten great accuracy without all the "proper" seating depth process. I found this accuracy advantage while fooling with the old military rifles that have a throat a mile long and you can not even get close to the lands and the round work through the magazine. Like has been said with the BAR use a small base FL sizing die. Also realize that the BAR is a hunting rifle not a target rifle and that minute of shoulder angel accuracy on game is still dead game. :D Have fun. [/QUOTE]
