do you intend to use only off the shelf ammo, or are you open to handloading for your rifles?
obviously, hand loading opens a huge increase in potential ammo choices , not easily available to non-handloaders
and will over time save you a significant amount of cash
yes it adds to the expense up-front for hand loading tools but the greatly reduced cost of ammo,
that results will over time greatly offset and amortize the initial cost,
youll also find you can use bullets not available in off the shelf ammo.
