Contact Glenn, AKA lar45 here, of White Label Lube. He can suggest one of his very good lube's to match your needs. I pan lube the 2500+ for my higher speed stuff, otherwise I just tumble lube with 45-45-10. But Glenn and Leah are good folks, and will help you decide if not sure what is best for your needs. Link below for their site.
