Hey guys need some help. I already have a rem long action that i have been wanting to use. I'm already set up for 243 so i thought why not people shoot 260 in long action with long bullets. What trouble might i encounter with feeding from long action mag? Also i like the krg bravo chassis system but it loos like it only uses acis cip la mags witch are even longer. Could they still possibly work? This will be my first build so I'm just learning. Thanks for any help you can provide .
