I have one, in the process of working up a load. I have shot some loads for my 308 ar, and it liked them pretty well. Learned a lesson, don't over tighten the stock bolts, will bind the bolt. I am using FC cases, SMK MK 175, WLP, and ar comp. I got mine w/out the vortex, put on a Nikon, but wish I'd stuck to Vortex. It is what I have on the others, but are PST, really good glass. People tried to talk me into other brands, but am very happy with the performance, and with a little work, it will shoot as well as my 24" AR.
