I use the Hornady One Shot lube, because I can't get the Midway spary lube anymore.
i have noticed that it takes quite a bit more One Shot to get my case nice and slick.
I like the spay lubes because they are easy to apply to a full loading block of cases. No need to lube the individual case, just spray all four sideds of the loading block and in 10 seconds, 50 cases are lubed.
