I too use Remington cases. Tried a box of Nosler cases and only lasted one reload, to soft I guess. My first batch of Remingtons are going on their 6th reload, but some of the primer pockets are getting really loose, so it might be time to open a new bag of Remington's. A little more prep work for the Remington's, but I don't mind cause it gives me the satisfaction knowing that I prepped them to the best of my ability.
