I used STP back in the 70"s. What can ya saw, the stuff worked! I've got a bottle of that Dillon spray and no use at all for it. Have that Hornady stuff like Imperial and only use it inside neck's to trim case's. No idea how you can tell if a case is lubed using that stuff, blind faith I guess. I've used the RCBS many years ago then switched to STP, STP must have been cheaper. Last 20+ yers I've used Hornady one shot. I doubt I'll ever change again, the stuff is wonderful. I don't doubt that the other thing's won't lube just as well but One Shot works and I'm gonna use it till it doesn work anymore!
The Lyman has a red case and the pad is muslin white. It has never been used and I have ink and I have ink pads with stamps. I do not use them but I have them just in case. And again, I have a no-name lube, I use it for the tuff to size stuff.. Anything works on all the other stuff and then; back to STP, I have two of the pull off lids, both are from Studebaker. Problem: The cans have collapsed slightly because of atmospheric pressure and heat.
Sorry, wrong. The best is my lube; Mink Oil Boot Dressing Cream. 100% reliable and no reports of any failures (but mebbe because not too many use this, but it's still 100% ).
Just like almost everything used in reloading, personal opinion/choice is more influential than how well something works...
