This bullet is designed to mushroom and retain its petals for virtually 100% weight retention.  All Barnes bullets are famous for deep, straight line penetration, broken bones and exit holes.  This version gives up a little BC to its tipped brother, but fits in shorter magazines better.  This is an excellent choice for all big game hunting at normal to longer ranges.


We measure each powder charge to within +/- .02 grains on our Autotrickler powder systems.  We seat each bullet with Redding competition seat dies on our Forster Co-Ax single stage press.   We load them one at a time!  Each round is hand measured for consistency and placed into our hard plastic, twenty count boxes.  Each box has a foam insert and neoprene strap to keep your rounds secure in the field.  This is loaded ammunition.
