These are the polymer tipped solid copper bullets. I've opened one box but decided not to load these. (2) boxes of 50ct. $32/box. FTF in Portland/Beaverton, or shipping is $3, for one or both. For more information, here's the Midway link: Barnes Tipped Triple-Shock X Bullets 30 Cal (308 Diameter) 150 Grain Sold in order of PM timing. These are also posted on Sniper's Hide. Thanks for looking.
