I have been using Nitro 100 for several years. I load a load around 1100fps at approx. 65-6700 psi. I noticed Recobs has American Select around $6 a 8# cheaper. I am getting a few bloopers which I think come from a combination of low pressure and worn out hulls. Has anyone tried American Select and Nitro 100? Is American Select cleaner, better ignition? This savings then got me to thinking about Rex 0 or 1. Where does Rex fit in the mix? Thanks for your help guys.
