If you are reloading .45 brass and experiencing intermittent priming problems on the Pro 1000 or Load-Master, you may be reloading Winchester 45 CAP NT (non-toxic) brass. Check the primer pocket, this brass has small primer pockets, instead of large as usually found on 45 ACP brass. If you intend to reload 45 NT brass, you will have to change your priming system from large to small.
