The Cast Boolit Forum is always running group buys for specialty bullet molds and this is one of the latest.

This one is for a .413-170gr Keith bullet. It is a six cavity Lee mold designed by one of the members of the Cast Boolit forum. It is a special run so when the group buy closes, that is the end of it.

Price is $70. Check out the link for further details and a drawing of the bullet.

This is an excellent chance at a bullet weight and design we don't see very often in .41 cal. Actually this is the first time I've seen a 170 gr Keith.
