When I got my Remington 660 in 6mm, my Father bought all of the Remington and Peters 90 grain BP 244 ammo that he could find, around 40 boxes, 'cause he thought that it was the best 244/6mm factory deer load available. They worked fine until I started to load my own with 100 grain Partitions and no longer needed the factory ammo. I still have 20 or so boxes of the Peters brand ammo in a plastic tote box at the storage unit.
