Berger Match Grade Target Bullets 6mm .243" BR COLUMN FB TARGET 1000/ct

"This bullet is the Berger 6mm BR Column. You?ll notice that there is no listed weight. This is deliberate since the overall weight is not as important as the overall balance of the bullet which is achieved with a specific internal lead column height. Due to slight variations in copper and lead material batches one lot may weigh 64.8 gr while another lot might weigh 65.1 gr or 64.6 gr. So long as the column of lead is the correct height to achieve the desired balance the overall weight is a by-product."
