I’m having this same thought for my Mini 6.5G, it doesn’t shoot to my standards so thinking of rebarreling it…let us know what barrel you end up with. I do like the Grendel, mines in a B&C stock with Jefferson Outdoors bottom metal…idk if bedding the stock would be worth it or not. I’ve tried 3 different 123gr Hornady loads SST, Black & BTHP and it doesn’t seem to like any of them.
