Well it's a long action so I probably will use LA cartridges at some point. So far I have only used it (Big Horn TL3) for the 6.5 CM and 6.5 PRC. I like to play around with things so maybe a 26 Nosler, 7mm PRC and who knows what else. I figured it would work well enough with a magnum magazine since my CM works fine in the standard LA mag. I was hoping by chance that there might be a mag designed specifically for that. One can hope.
I currently have two Long action rifles and three short action rifles. In six months from now, I may have more or less of those. Also various barrels. Thanks for your reply.
