I picked up some once fired Winchester nickel .500 S&W cases and tried to resize them in with my RCBS steel sizing die. The long heavy walled straight cases of the .500 are tough to size and the nickel only made them more difficult.
While the regular brass cases aren't too bad if properly lubed the nickel cases were a challenge even in my A2 press with my normal Lee water based sizing lube. The cases were hard to push into the die and chattered on the way out. I though for certain I was going to pull a rim off and stick a case in the die.
Searching for something better I tried a number of other lubes I had including some of the Imperial Sizing die wax - that stuff was useless in any thickness - now I know why I still have a nearly full tin left after all these years! Hornady Unique lube was almost as bad although it works OK for other cartridges.
I tried some RCBS Case Lube-2 wiping it on with my finger as I picked up the cases to size them - same method as I use with the Lee lube. Not much good either. On other cases the RCBS stuff works about like the Lee stuff but is messier to use so I normally go with the Lee lube.
Then I remembered I had a can of Hornady One Shot someone had given me. I sprayed the cases down, let the stuff dry for a few minutes per the directions and then tried to size them after first cleaning the die and giving it a shot of One Shot. To my pleasant surprise - the cases with lots of lube on them sized with very little effort. Ones with less lube sized with about the same effort as the Lee stuff. A relatively thick even coat was a necessity.
After sizing a few cases and examining them I noticed they had an odor I recognized. The One Shot smelled just like the RCBS-2 stuff and even looked the same on the cases. Ah-Ha!
Back to trying the RCBS stuff BUT this time I waited a few minutes for it to dry. Guess what - it worked just like the One Shot when it was dry with a good thick even coating. Cases gluided in and out of the die with little effot.
Thinking the dry state may make a difference on the Lee stuff I also tried letting the Lee stuff dry but it didn't seem to make much difference.
I guess I could dilute the RCBS stuff with alcohol or something and spray it on the cases like the One Shot but I'll probably stick with applying the stuff with my fingers for now. I don't size that many nickel .500 cases and the Lee stuff works fine for everything else.
Anyone else make the conection between the RCBS and One Shot stuff or use the RCBS-2 stuff once it has had a while to dry?
