started to reload for my sons 257 weatherby only to find out i am out of case lube. the spray lubes dont seem to be enough for the long weatherby cases. looked around the garage and saw some grease we used to use when rebuilding engines and decided to try some. i used it just like you would any other case lube and it worked really well. next time you are out of your favorite lube give it a try. you should be able to pick it up at any auto store.
