[QUOTE="Osage48, post: 2794535, member: 1176"] I tried some IMR4227 and it worked just a little better. So I took all the weights out of my buffer and cut about 3" out the spring (it was a lighter spring already) and used motor mica lube and it cycles most of the time but still does not lock the slide back on the last round. I said it had a mid length but the gas tube is about 8" in length. One thing I noticed is that I am having to use about 10% less powder than published to get below the sound barrier. It is the same with different powders. I guess I will need to open the gas port. Can't think of anything else to do. [/QUOTE]
