If you live in a place where it gets cold often, or during the winter time, you will get better results using 5w30.Otherwise 10w30 oil is good enough, i usually use 5w30 all year round.ating Newest Oldest.

Several years ago someone on the 10mm-L asked: If I understand it right the 10mm and .40 S&W bullet are one in the same. â¦ What are the technical reasons as to why you are unable to fire .40 S&W in a 10mm pistol the same way you can fire 38 Special in a gun chambered for .357 Magnum..he operative term here is  Stand-Off1 , where the .40 S&W (actually 0.03mm narrower than the 10mm) is somehow slipping past the extractor and head-spacing on the case mouth deep in the 10mm chamber, leaving 1/8 of stand-off between the case head and the breechface.
