I've been reloading my .223 AR with Win 748 and Federal small rifle primers. I've almost used all of my Federal small rifle primers up and will be using CCI No 41 primers soon. I plan on using a reduced starting charge, but my Hodgdon handbook only shows 26.3 gr and that is what I have been using with the federal small rifle powders. Does anyone have any experience with CCI no. 41s and Win 748? I plan on the standard 10% reduction for my starting load. Hopefully the action cycles!
