Either a) finding ammo, as it is only produced in small quantities now, or b) finding brass.
If you're a reloader, stock up on brass now. After the initial full-length sizing, neck size it only, to make it last.
If you have the brass, you can always find bullets, primers, and powder.
Hmm.. good tip I do reload so I will keep that in mind that is why I was considering rebarreling it in a diffrent caliber but im not sure what yet want something with 1000 yd performance
One reason 6mm Rem never really caught on is that it is really an intermediate length cartridge, and is best suited for a long action. Remington put it in short actions, and caused issues with having to seat heavy bullets deep in order to work out of the 3.050" magazine box. I recommend a long action for a build, but if you have a short action, it can be made to work just fine.I was wondering if a 6mm remington is designed for a short action or long action
Remington makes brass for the 6mm Rem, it is available (I have a brand new bag of 100 downstairs in the shop). No loaded ammo, but brass is available. Or, as taylorce said, you can form it from several other cases, 7X57 or 257 Roberts would be easiest.Yes brass will be difficult if you want correct head stamped brass. If you want to form brass it can be made out of 7X57, 8X57, .257 Roberts brass as well
