Is the 6.5. Going to be fairly available. Off the self in the future. Or is; Hornday:
now the only source?
I am not a reloader.
Just buy a case of Hornady in the size/flavor you want and be done with it. All your ammo will be from the same lot so you shouldn't have any issues from one box to the other.
Save all your brass and you can use them for reloading in the future if you decide to get into it.
