well, just trying to do some research for tax time. i really want to get into some larger cailbers with this platform. im not sure what caliber i should go with. i want to use an AR for deer hunting. but what do i pick? 6.5 grendal, 6.8spc. 300 blk, 458 socom. and then theres the ar10 in 308. hmm well i know at some point i will have an ar 10. but for now what caliber should i try to focus on more. ive read some stats and the 6.5 is looking pretty awesome. i reload so i dont think ammo would be as hard to come by once i got my componets.
