I have always thought lube type does not matter much as long as it does its job. I was so wrong! I have been playing with cast loads for my m1a and tried quite a few lubes, including Hi-Tek coating. Never any leading, always a clean bore, but so-so accuracy. Until I tried a stick of carnauba red, then my groups shrank at least by half, consistantly. The only thing I don,t like is it is a bit sticky. I understand the blue is very similar but not so sticky. Has anyone tried both of these lubes with the same load otherwise? What was your results? Same accuracy or did one work better than the other? I need to place an order and do not want a bunch of blue if the red is better. I know I will probably just have to try it and see if it works for me. Let me know your results, thanks!
