This very interesting new bullet was originally developed for the Sierra Prairie Enemy 6.5 Creedmoor ammunition. Tremendous explosive performance on even the smallest varmints has been its history. So many requests for the bullet as a reloading component for use in the wide array of 6.5mm cartridges has prompted Sierra to offer this bullet. Explosive expansion is a given. True match-accuracy has been easily achieved in all applications. Great varmint bullet and excellent short-range match bullet as well. These would be most excellent in the 6.5 Grendel and most other of the 6.5mm cartridges for prairie dogs groundhogs rock chucks up through bobcat and coyote.
